In pictures: Picasso and Africa

'Picasso and Africa', an exhibition that puts works by Pablo Picasso alongside the African sculpture that inspired him, opens this week in Johannesburg.

"It never makes sense just to hang pictures unless there's an idea behind it," explains Marilyn Martin, director of the SA National Gallery. "It was self evident the theme had to be Picasso in Africa because that hadn't been done before." Picasso's 1908 Sitting Nude is seen with a mask from Baule in Ivory Coast.
