From one to twenty, this bright, basic counting book puts forth a given number of items for each number, e.g., four ponies. Lifting a flap reveals related items of the same number: Four horse shoes show up one pony's saddle. The grand finale is twenty presents, each just a lift of the flap away from being ""unwrapped."" Should the sturdy little doors and flaps fall off--as inevitably they will--the book still works.
