COVER: Paul Klee had the kind of innocent magic that could evoke a wistful human face from the simplest of geometric forms. In Senecio he does it with circles for head and eyes, a straight line to suggest a nose, and two tiny rectangles where one would expect a mouth. “It is not my task to reproduce appearances,” he once wrote in his diary; “for that there is the photographic plate … but my faces are truer than life.”
