1938 Wheaties "Jack Armstrong" Premium, Magic Answer Box. Toy is MINT, box is like new. This is a very awesome and hard to find premium. Top center has a window to display an interior silver metal pointer that lines up with a series of answers printed on the tin above the window opening. The user poses a question and then places a thumb over an area on the side of the box which has a small opening. Heat causes a thin cellophane strip on the interior to then curl, thus moving the finely balanced pointer. It takes a few seconds for the heat to build up but the needle will move to "try again" to "no" to "check!" to the final "wow" answer at the far upper right. Very rare to find on that still works properly.
