This is a very rare an unique art print in it's raw form. This is how lithographs come off the press. This one features handbills down the right side. These would usually be trimmed down into the art print itself and the handbills separate. 

Proof sheets are typically made to show print quality before the print run. They are rare and often kept by the artist.
