Yummy!
Every child should have this book in their personal library. I bought this for my son when he was 8 years old, I found it later and bought it for my grandchildren, and then I managed to find it again on Alibris - this time for the granddaughter of a close friend. Even I enjoyed laughing over the incredibly clever pop-ups (the "book" is ALL pop-ups) and it looks just like a nice juicy hamburger.
Pure whimsy - what an imagination the author has to "write" such a delightful bit of nonsense. Better than a Dr. Seuss book!
