Pink Floyd - Animals 1977 Successful billboards leverage the most obvious asset: their enormous size. Very little text was desirable. Compelling artwork, the recording artist’s name, and the title of the record were more than enough, and even that information was sometimes jettisoned. Pink Floyd had a strikingly surrealistic visual style to accompany their unique music. The covers for their albums like Animals were graphically stunning and easily translated into compelling billboards.Picture: Robert Landau/ Rock ‘n’ Roll Billboards/ Angel City Press
