In chatting online with talented Swedish designer Magnus Häglund (see his excellent personal designs for H. G. Wells books, done as newspaper front pages, here), I learned of a book I can't believe I didn't already know about: a Swedish modern classic, a dystopian novel about a totalitarian future with the population kept under control through the use of truth drugs and the like. It's Karin Boye's Kallocain, from 1940, and my determination to read it made me thrilled to discover an English translation has been put online by the University of Wisconsin.
There's nothing like a real book, though, and in searching for covers, I found a beauty, from a Norwegian publisher, Lanterne.
The same publisher had some other, wonderfully psychedelic SF covers:
Many of these have a very David Pelham feel.
