Alberto Giacometti modeled his Grande Tête Mince (Grande Tête De Diego) on his younger brother Diego, who inspired numerous variations on the theme of head and bust sculptures of the 1950s and whose physiognomic similarity to the artist invested these projects with an autobiographical narrative. Charles Moffett and Elizabeth Gorayeb discuss this profoundly expressive sculpture on offer in the 6 November Impressionist & Modern Art sale.
