A 1932 portrait by Pablo Picasso of his young lover and a pioneering 3-D Andy Warhol painting of the Statue of Liberty are expected to sell for at least USD 35 million each, but could fetch much more when they are auctioned next month.
Works by artists Andy Warhol and Alexander Calder will be sold at a charity auction in November for orphaned and other vulnerable children in Africa, Sotheby's said on Tuesday.
