The Learned Duck. Flein: R?diger Deutsch, ca. 2000. A spectator removes a drawer from a low platform supporting twelve wooden cylinders and a central brass bowl with a small duck in it. The volunteer rotates the arrow inside the drawer toward a question he wishes answered, and returns the drawer to the platform. The duck then swims over to one cylinder, which is opened to reveal a message that answers the thought-of question. Based on an effect first described circa 1800. Platform 11 ? x 11 ? x 4 ??. Near fine. One of perhaps six manufactured. With two extra ducks.
