Here is a wishing fantasy about a boy who finds in his attic an umbrella that can produce anything he desires -- and his wishes run wild. He is snowed under by money, toys and candy bars. When the sun comes out and he wants to go out and play, he wishes all the clutter back where it came from, retaining only the little black dog. The umbrella blows away and finds itself another attic. It's a very slight story; the possibilities are not very well developed. The book is not saved even by the illustrator, Roger Duvoisin. His full color pictures sparkle, but the others are rab.
