During the 60s, a lot of stuff is really cheesy. Elvis' stuff, The Beatles' stuff unfortunately until maybe the late 60s had fairly bland artwork. They would just cover with a group picture. Some of the lesser bands would get cheesier psychedelic stuff. If you're going to lash on to the fad of the time (mid to late 60s), all sorts of people would just slap on these swirling colors. The Moody Blues, they are a British band, and their most famous record "Days of Future Passed" has a cheesy, rainbow colored psychedelic cover on it; it is kind of corny. Usually the main important LPs have the best cover art and if they are really good hopefully they will get your attention.
