Inspired by last year's tome on 70 years of cover designs at Penguin, this Flickr gallery attempts to collect examples of the last few decades' worth of Penguin/Pelican jackets. If anything, the starkly crude, mod, and/or trippy designs are testaments to doing a lot with relatively limited graphic resources. Of course, you've also got plenty of purely objectionable cases of crap abstraction for abstract subjects, such as the coma-inducing Psychiatry To-day.
