When your target picks up this matchbox from the table, it immediately wobbles in a most surprising manner. The box contains a clockwork motor with an eccentric weight attached. As soon as the box is lifted the motor starts. Note the tiny Davenport demon head trademark and the initials L.D. on the front of the box. This Demon Wobbly Matchbox was sold in an eye catching box printed in a style typical of Davenports at the time.
