"One of the most interesting lithographs [Picasso] produced during that time was a bullfighting scene in which he applied the principle of the papier collé to lithography. He took a piece of lithographic paper, applied it to a rough surface and rubbed it at each end and at one or two spots with a lithographic crayon until those areas had the grainy texture of a Max Ernst frottage. From the darkest of these parts he cut out the figure of a picador and pasted it down in the white area near the right hand side. Other elements he pasted in with the lithographic ink, on each side of the bull he had a picador, at the left a picador in white...and on the right in black."
