Storm Thorgerson and Aubrey Powell, working under the art studio umbrella of “Hipgnosis” created the album art for some notable albums. Pink Floyd’s concept-album masterpiece, ‘the Dark Side of the Moon’, is one of their most notable.
George Hardie, another U.K. artist, created the last two images, which were actually published as stickers on the first pressing of the album (The ones you are seeing in this post were not easy to find, because they were never stuck to anything:)
The blue “Pyramids” poster is the European and International Release version. It also featured a different version of the concert photo “Elements” poster, with the images aligned vertically. The green “Pyramids” poster came folded into six squares, so as to slide into the album sleave. Consequently -with all the posters- the first prints came folded. Be aware of the differences, because a nice, playable vinyl from the first pressing can set you back $70-80, and that’s without the posters.
