Resting on a low stand is a cover with a door in one side of it. The performer lifts the cover and reveals a plain black block which he removes from the stand, displays and then returns to its original position. This, explains the performer, is supposed to be an alphabet book, but the makers forgot to finish it. He then invites several assistants to help him to change the plain cube into a colorful alphabet block by magic. Includes instructions. Block shows some wear, else in good condition.
