Analytic cubism (1909–1912) is a style of painting Picasso developed along with Georges Braque using monochrome brownish and neutral colors. Both artists took apart objects and "analyzed" them in terms of their shapes. Picasso and Braque’s paintings at this time have many similarities. Synthetic cubism (1912–1919) was a further development of the genre, in which cut paper fragments – often wallpaper or portions of newspaper pages – were pasted into compositions, marking the first use of collage in fine art.
