Judging from the two knobs at the bottom corners and the grid of lights, it's an example of an extremely early attempt at making an electronic Etch-a-Sketch. Unfortunately, the low resolution of the 'screen' due to the size of the bulbs made it impossible to recognize any of the pictures drawn on it, and the inventor was never able to acquire relays small enough to allow him to use grain-of-wheat bulbs on the display; the smallest such a device could be was the size of an upright piano, which was impractical for a child's handheld toy.
