Two original Banksy artworks owned by Friends actor Matthew Perry have sold for £975,000 at auction in the US.Girl with Balloon and Nola went under the hammer on Friday, which featured 127 items from the actor's estate after his death in October 2023.Money from the auction - more than $2.2million (£1.65million) - will go to the Matthew Perry Foundation, set up after his death to destigmatise addiction and help others' recovery.Mr Perry, who played Chandler Bing in the New York-based sitcom, died aged 54 after he accidentally drowned in a jacuzzi at his Los Angeles home while on ketamine.During the auction Girl with Balloon - which features two spray-painted stencils on separate canvases and depicts a child reaching for a red heart-shaped balloon - sold for £709,674 after an intense bidding war.After the 25 per cent buyer's premium the price rose to £887,093.One of Banksy's most recognisable works, Girl with Balloon first appeared as a graffiti mural painted outside a Shoreditch shop in London in 2002 and at the capital's Southbank in the same year.On its second outing the artwork was accompanied by the caption: 'There is Always Hope.' Girl with Balloon, an artwork which first appeared in 2002 on the streets of London, sold for almost £900,000 Nola, created during Banksy's visit to New Orleans three years after Hurricane Katrina, sold for almost £90,000 More than 100 items from Matthew Perry's estate were auctioned on Friday after the actor's death in 2023A simple piece, it inspired a range of personal reactions from hope to loss.Nola - a screenprint in colours on Arches wove paper of a young girl holding an umbrella in the rain - fetched £70,967 and was the first Banksy Mr Perry bought, Heritage Auctions said.Adding in the buyer's premium, it sold for £88,709.Created in 2008, it shows a young girl holding an umbrella while she feels for the rain, at first glance showing shelter and calm.But the protection is an illusion - the rain comes from the umbrella itself while outside is dry.According to Banksy Explained: 'What should shield instead exposes. What should reassure quietly fails.'Nola was created in August 2008 when Banksy visited New Orleans in the US, leaving around 15 stencil murals to mark the third anniversary of Hurricane Katrina.The piece was seen as a commentary on the failure of systems designed to protect the population, with the name featuring the initials of New Orleans and the state code of Louisiana.Both artworks were signed by the artist.Girl with Balloon fetched the most at Friday's auction, with an oil painting by Mel Bochner being the second most expensive item at £103,000 before Nola in third.The 2004 script for The Last One, the Friends final season finale, signed by the cast was sold for £70,200.Other items in Mr Perry's estate auction included a TV Guide display (£3,750) and a custom Chandler Bing bobblehead (£2,800).Batman memorabilia including a custom ping pong table and a The Dark Knight Rises watch also featured and went for £8,900 and £16,000 respectively in the sale, held at the auction house's Dallas, Texas office.Brian Chanes, Heritage Auctions' senior director, previously told the Daily Mail of the items' significance to Mr Perry.'The outpour of enthusiasm and support and adoration for Matt has been amazing,' he said. The former Friends star accidentally drowned in a jacuzzi at his Los Angeles home while on ketamine. He was 54A copy of the original Friends series outline, originally titled Six of One, described the premise of the series and the 'friends and lovers' it set out to follow.'This was the name of Friends, Six of One, before it became Friends, but this is basically an outline,' Mr Chanes said of the script.The outline reads: 'Six single people living in New York is about friends and lovers, Ikea furniture, cappuccino, bad date, Spanish soap operas, and Mr Potato Head.'Also up for sale was the original Six of One pilot script which sold for almost £40,000. Magazines collected by Mr Perry's publicist, including the TV Guide editions, offered an insight into the peak of Friends fame.'I know they just look like regular magazines and plaques, but one of his publicists, his job... everything that he appeared in, he ended up getting him a copy. And so that's what you see, a portion of it right here,' Mr Chanes said. The collection includes the outline for Six of One, the original name for the sitcom that would become FriendsBefore his acting career, Mr Perry grew up playing tennis and was a keen fan - his racquets were up for sale at Friday's auction, their broken strings showing their use.A set of four racquets in a Wilson bag sold for more than £4,600.'Obviously well-worn, you can see the gut strings are popped on a couple of them,' Mr Chanes said.'He was heavily influenced by sports, especially tennis,' he added.'He loved hockey too because he was from Ottawa but he felt particularly motivated by his idol Jimmy Connors.'Much like Mr Connors - the former tennis player, commentator and coach - Mr Perry devoted himself to the sport before switching to acting.'He would play up to ten hours a day when he was a kid,' Mr Chanes said.'He was really accomplished, he was actually playing tournaments in Canada and when the family moved from Ottawa to LA, there was a lot more competition, everyone has a tennis court out here and you can play year round, unlike Canada. Mr Perry, pictured with his co-stars Courteney Cox, Jennifer Aniston, David Schwimmer, Lisa Kudrow and Matt LeBlanc, played Chandler Bing on the sitcom for ten years'And so he realized it wasn't necessarily in the cards for him to play professional tennis. But it meant a lot to him. And he still played.'Featured on the website of his foundation is a quote from Mr Perry describing its aim: 'When I die, I don't want Friends to be the first thing that's mentioned. I want helping others to be the first thing that's mentioned. And I'm going to live the rest of my life proving that.'Mr Perry battled addiction for years, a struggle that intensified during his time on Friends, when he became one of the biggest stars of his generation.His rise to fame alongside Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc and David Schwimmer on the sitcom, which ran from 1994 to 2004, was overshadowed by his addiction.After his death his former colleagues released a joint statement describing themselves as 'more than just castmates' and 'a family'. A 'Chandler Bing' card, presumed to be a gag gift, were among Mr Perry's belongings auctioned in Dallas on FridayMr Perry openly admitted his condition frequently interfered with his work during those years, as he recounted in his 2022 memoir Friends, Lovers, and the Big Terrible Thing.Five people have been convicted for their part in his overdose, including Perry's drug counsellor, his 'Ketamine Queen' drug dealer Jasveen Sangha and two doctors.Last month Mr Perry's former assistant Kenneth Iwamasa, who injected the star 'repeatedly' with ketamine on the day he died, was sentenced to more than three years in prison after pleading guilty to one count of conspiracy to distribute ketamine, causing death.The actor's final request to Iwamasa was 'shoot me up with a big one' before the injection was administered.Iwamasa, 60, was the first of the five people implicated in Perry's death to reach a plea deal with prosecutors in August 2024.In addition to his 41-month prison sentence, Iwamasa was ordered to pay separate fines of $10,000 (£7,490) and $100 (£80), and be on supervised release for two years.He must hand himself in by July 17 to begin his sentence.
