Big "E"

A large square sign printed with a large “E” on each side is shown. The magician patters the “E” behaves in a bewildering way; first, they face the same way, then they appear to be printed at right angles to one another, and finally, they point in opposite directions. If that was not confusing enough, the sign opens into a folder with a large red square on one side and a large green dot on the other. Opening and closing the folder makes the square and the dot jump back and forth. For a surprise ending, the square turns to blue and the dot to yellow. Includes instructions. Mild soiling and toning, else in good condition.
