Passage: There was a distinct difference between Kahnweiler's Cubists and the Salon Cubists. Prior to 1914, Picasso, Braque, Gris and Leger (to a lesser extent) gained the support of a single committed art dealer in Paris, Daniel-Henry Kahnweiler, who guaranteed them an annual income for the exclusive right to buy their works. Kahnweiler sold only to a small circle of connoisseurs. His support gave his artists the freedom to experiment in relative privacy. Picasso worked in Montmartre until 1912, while Braque and Gris remained there until after the First World War. Leger was based in Montparnasse. Question: Where was Leger based around 1912?
Montparnasse
