Marc Chagall Banks Of The Seine Signed Lithograph

Marc Chagall Banks Of The Seine Signed Lithograph I'm not an art expert so I don't really know a lot about this lithograph. I was told by an art dealer friend that it was a signed lithograph. I have included a photo from a piece from art net for reference. There are others with the same name out there from a book, but the coloring is different. Measurements: With Frame: 12"W x 16"H Art itself: 8.5"W x 11.5"H
