One very psychedelic, very colourful album cover I found recently - not by WRC for a change, but RCA. It isn’t dated, but it is from 1972 – being part of a series designed by Bob Pepper.
I recognised the style of design straight away, but didn’t know much about Bob Pepper, so pieced together some information from crumbs on the internet:
Bob Pepper, now retired, began his work as an illustrator in 1962 and became very well-known in the 1970′s and 1980′s for his decorative style. He produced a number of covers for Sci-Fi/Fantasy paperback covers, and a well-known series of 6 Philip Dick books in 1982 for Daw. He is also very well-known for the artwork on the ”Dragonmaster” and “Dark Towers” games.
A very smart site I discovered, by immensly talented artist and designer John Coulthart, has a good entry on Peppers work too.
The first image is the Album Cover for the “greatest hits” series by RCA which Bob Pepper designed a number of covers for. The remaining images are ones I found on Flickr by just typing in “Bob Pepper” . The first 3 of course are from the series of Philip Dick covers, but I actually like the last one the most – probably because it has an astronaut! – although I love the font used there too. You can click on the book covers to go to the Flickr stream where each came from.
