‘You take pictures, I paint’: Picasso friend’s photos given to Swiss museum

War photographer David Douglas Duncan rang bell of artist's home one day, leading to 17-year friendship

One hundred photographs chronicling the private world of Pablo Picasso up to and after his death in 1973 at the age of 91 have been donated to the Musee de l'Elysee in Switzerland.

The pictures are a sample of 25,000 taken of the artist by David Douglas Duncan, an American war photographer who first met Picasso in Cannes in 1956.
