Record album covers from the 50s and 60s (and to some extent, the 70s) had some of the greatest bizzare photography you’ll ever see in your life.
Finally, I’ve found a website that puts some of the greatest ones on display. Check out the galleries.
Another decent site for old album covers is When LPs Roamed the Earth.
Not all old albums had music on them either. For example-
this and this look particularly interesting.
Les Baxter and Martin Denny had some absolutely beautiful covers. In fact, Baxter’s “Space Escapade” has got to be my all-time favorite LP cover.
They just don’t make ’em like this anymore, folks! And let me tell you – they’d sell a whole lot more albums nowadays if they did!
