'Le Violon' from 1914 is one of the great examples of synthetic Cubism by one of the heroes of the period: Georges Braque. Jeremiah Evarts, Head of Evening Sales, Impressionist & Modern Art, discusses the relationship between Picasso and Braque and how their artistic dialogue was nothing short of revolutionary. Le Violon will be offered on 4 November as part of The Collection of A. Alfred Taubman Masterworks auction. Visit sothebys.com/taubman.
