Cover art is a big part of a vinyl record's appeal, and some of the greatest artists of all time have created cool artwork to accompany killer cuts- Robert Crumb, Roger Dean, H.R. Giger, Edward Gorey and Andy Warhol, just to name a few.
Over the years many of these cover artists have chosen to take the visual appeal even further by adding hidden images to their album artwork, like easter eggs for music lovers to discover while they listen to their new favorite album.
