“Picasso’s new method made it possible to ‘represent’ the form of objects and their position in space instead of attempting to imitate them through illusionistic means. With the representation of solid objects this could be effected by a process of representation that has a certain resemblance to geometrical drawing. This is a matter of course since the aim of both is to render the three-dimensional object on a two-dimensional plane.... [H]e can show it from several sides, and from above and below.” —Daniel-Henry Kahnweiler, 1920 "Ma Jolie".

Guitar, March 1913, Cut and pasted newspaper, wallpaper, paper, ink, chalk, charcoal And pencil on colored paper. 26 1/8 x 19 ½” - MoMA Synthetic cubism “At this point Braque’s introduction of undistorted real objects into the painting takes on its full significance. When ‘real’ details are thus introduced the result is a stimulus which carries with it memory images. Combining the ‘real’ stimulus and the schemer of forms, these images construct the finished object in the mind.” —Daniel-Henry Kahnweiler, 1920
