I want to know the answer to the following question:
Where did Braque and Gris stay until the end of the World War I?
All the background I'm provided with is that "Prior to 1914, Picasso, Braque, Gris and Léger (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.". Is that enough to answer the question?
