Waco, 1950s
7.5 inches tall

One of the rarest robots, and also one of the most intricately designed, the Hook stands tall on many collectors' must-have lists. There are two variations, the other is light blue with silver details.

The toy features a primitive friction/fly wheel mechanism -- rev the toy a few times and Hook rolls forward. At the same time, the robot's head turns side to side.

The Hook robot gets its name from the unusually-shaped antenna on the back of its head.
