"There is no comparable book in the recent Klee literature. Marcel Franciscono introduces the reader to the artist and, in turn, to all the major Klee problems uncovered by specialists working in one or another area of the master's work. The result is a rich symposium in which all these opinions, as well as the relevant biographical facts, are returned to individual works of art, illuminating them exquisitely. In this low-keyed fashion emerges the splendid general study that is required of every generation for a great artist."
