Painted in lavish tones of seductive pinks, deep crimson and scarlet reds, Rufino Tamayo's Sandías y naranja, 1957, stands a radiant symbol of Mexican identity and vibrant example of Mexican Modernism. Previously in the collection of American film legend Audrey Hepburn, this iconic still life leads Sotheby's Latin America: Modern Art auction on 22 November in New York.
