While preparing a lecture about the world of cartoons I noticed that in fact my collection of Searle books is not so extensive. One of the books I was curious about is this one: Zoodiac. I eventually decided to buy it and easily found it on eBay. Hereunder you can see an impression of the book (Pantheon Books New York, ISBN 0-394-50062-8,1978).
Jean-Marie already owned this book and wrote about it a time ago on our blog (Ronald Searle The Great (part 6) - His so human bestiary) and in his article you find some more pictures and information.
I have doubts about astrology and the zodiac, but I believe in the magic of the Zoodiac cartoons Searle drew for this book.
