Richard Bober: Hitchcock: Don 't Look a Gift Shark in the Mouth

Original cover illustration (revised!) for one in the famous Dell series from Dell Books, this one from 1976 - and one that for some reason Richard changed after the fact.  In acrylic and oil on masonite, 22" x 15" I am not sure of the condition here, it looks like it's covered with cobwebs. - hoping for a better photo next week!  Meanwhile I wanted to be sure to offer it....the photo doesn't show a signature....If the work is unsigned, a letter of authenticity will be provided by the estate.
