Artwork by one of the most influential artists of 20th century raffled to fund Alzheimer’s research

His work is consistently ranked among the world’s most expensive art, with paintings fetching more than a $100m at auction. But you no longer need to be a multimillionaire to own a Picasso – for €100, anyone in the world has the chance to walk away with a painting by one of the most influential artists of the 20th century.

The French charity Alzheimer’s Research Foundation announced recently it was raffling Picasso’s 1941 portrait, Tête de femme, which is worth more than €1m, to a single winner. Proceeds from the tickets will help fund Alzheimer’s research, one of the leading causes of death and disability worldwide.

The project, entitled “1 Picasso for 100 Euros”, is the first of its kind in the world, and a natural continuation of Picasso’s legacy, according to his grandson Olivier Picasso.

“My grandfather was very generous, but he was also discreet,” Olivier told the Guardian. “He helped his family, especially my grandmother Marie-Thérèse [Walter]. He helped friends. He helped people in need during the civil war in Spain, during the second world war, and even after, in the 50s and 60s.
