In 1965 Roland Penrose visited Picasso in the hope of negotiating the acquisition for the Tate Gallery of a major work. A trustee of the gallery, Penrose drew upon his relationship with Picasso, as a friend and his first biographer, and on the success of the Tates retrospective five years earlier. Unexpectedly, Picasso agreed to the sale of The Three Dancers, 1925, the painting he considered one of his two greatest alongside Les Desmoiselles dAvignon, which had long been at the Museum of Modern Art, New York. It was the first time Picasso had sold a work directly to a public museum, and was seen as a reflection of the importance that he placed on London. In 1967, Penrose curated an exhibition of Picassos sculpture, again at the Tate Gallery, securing the artists reputation as one of the great innovators in three dimensions as well as in two. Since then, Picassos influence on British art has continued uninterrupted.
