POP-UP. BAG OF FUN. Chicago: Whitehall 1951. There are 6 books (5 3/4 x 6 1/2"), stiff pictorial wraps in fine condition housed in the original cardboard carrying case (case repaired). The case simulates a piece of luggage with a handle for carrying. Each book has a great color pop-up inside the cover plus each book has either 2 or 3 additional books inserted into a pocket. The inserted books have various activities for the child to do. Titles include: Teddy and Dolly, Jumbo and Bunny, Birds of America, Puss and Chicky, Wild Animals and Farm Friends. Unusual and amazingly complete.
