The fact that the 1912 exhibition had been curated to show the successive stages through which Cubism had transited, and that Du "Cubisme" had been published for the occasion, indicates the artists' intention of making their work comprehensible to a wide audience (art critics, art collectors, art dealers and the general public). Undoubtedly, due to the great success of the exhibition, Cubism became recognized as a tendency, genre or style in art with a specific common philosophy or goal: a new avant-garde movement.
