The fifth studio album to be released by Pink Floyd was "Atom Heart Mother", released in October 1970. It was the band's first album to reach number 1 in the UK and the first one to not feature their name on the cover or contain any photographs of the band. This was a trend that would continue throughout the 1970s and beyond. This artwork is now available as a 500 piece jigsaw puzzle printed on high quality board. 500 pieces. Weight: 490g.
