The cover art, and all related artwork for "The Mollusk", was done by Storm Thorgerson, the graphic designer who designed many of Pink Floyd's album covers, including "The Dark Side of the Moon". After Thorgerson heard the album, he liked the band so much that he decided to do all the related promo and poster art in addition to the cover art for which he was hired, for no extra charge. As a result, all artwork, including all print ads associated with "The Mollusk" at the time, were done by Thorgerson.
