The magician, with the aid of these miraculous slates, can cause any brief message to appear. The slates are shown devoid of any writing at all before the trick begins. The name of a selected card, a spirit message from beyond, or anything else, then appears on one slate, written in chalk. Carry it in your pocket.
Always ready to work. Easy in operation. No sleight of hand is required. Measures 2.5" x 3.25".
