This poster was submitted to George Harrison to be used as the album cover for "All Things Must Pass" (please see letter from Tom Wilkes to George (http://www.allthingsmustpass.com/album/index.html click on 'A' for 'Album Art'') but was ultimately rejected because George was not comfortable with depiction of the nude blonde maidens. According to Mr. Spizer’s book, only 5 artists proofs of the finished poster were made.
