Ironically the cover of Pink Floyd’s Animals album, which most of the obits are using to illustrate his work, wasn’t his idea. Thorgerson made some proposals to the band for the album cover but they didn’t like any of them. Roger Waters pedalled round south London on his bike taking photos and took some photos of Battersea power station and came up with the idea of flying a pig over it as a symbol of hope. Hipgnosis then agreed to stage the shoot. Thorgerson later included the Animals album cover in a book of Hipgnosis artwork and Waters fell out with him as it was his idea. Waters never worked with him again.
