A small group of Montmartre artists led by Georges Joubin and Pierre Bonnard founded an artistic movement which they named L’École de Montmartre in 1928.
The collection consists of over 100 items ranging from handwritten meeting minutes, letters, and calling cards, to contemporary newspaper clippings, the official application for association filed with the French government, copies of their manifesto, and the first three issues of their official journal, Témoignages, each containing original signed engravings.
