Anything by Hipgnosis.
Note to the young and under educated:
'Albums' were a 12" piece of vinyl that held an audio recording of someone that actually had talent. This recording was accessed by a fine needle that followed a spiral groove in the vinyl platter which was then decoded electronically to then burst your eardrums via a complicated array of turntables, amplifiers and loudspeakers. They were often incased in cardboard sleeves showing various images, lyrics and information that didn't need to be accessed via Google.
Plus they were brilliant for skinning up on...
