Mickey Mouse box found with Lewis Davenport apparatus

The purpose of the box is to instantly transform Mickey Mouse’s head into a white question mark. The box was found with Lewis Davenport’s stage effects, but we do not know how it fitted in to an overall effect. The Mickey and Minnie Mouse automata (Ref. no. N834 and N833) may well have been part of the effect, as well as De Kolta’s Expanding Die. The reason for believing that the die was part of the effect is because there is a cover for the die in red material with a white question mark on the front of it.
