When 271 never-before-seen Picassos appeared in 2010 the art world was stunned.
Included in the works -- a small sample of which can be viewed in the following slides -- were six sketches, 28 lithographs and nine cubist collages. There were also two, full sketch pads with 81 drawings.
The Picasso Portfolio
The stash contained works spanning more than 30 years from 1900 to 1932. Some were preliminary sketches of well-known works displayed in museums and galleries around the world.
