TPS (Japan) Educational Tin-Litho Pet Pooch Counting Trick with Original Box

This excellent condition 4" tall tin pooch is wearing a graduation cap while he teaches children to perform math by pre-setting the answer to the math problem on the bottom of the toy by using a side dial.

The dog's head moves up and down when you turn the dial, and the toy is placed on a flat surface. The toy worked well when tested.

The box is in good condition, with what appears to be a razor-blade-like cut down the front side, but all paper, words, and graphics are present on the box and are easily readable.
