Mr. Men trail
It's 55 years since the first Mr. Men book — Mr. Tickle — was published, and Battersea Power Station celebrates with a free interactive Mr. Men/Little Miss trail, weaving its way through the venue. Pick up a map from the Guest Services desks, and set off in search of characters from the children's book series — collecting free downloadable 'gifts' as you go along.
Until 30 August.
