One of my favorite toys! 1960 Ideal Toy the Mr. Machine. I played hours with this big guy. Mr. Machine was a robot-like mechanical man wearing a top hat. His body has a giant windup key at the back. When the toy is wound up it walks, swinging its arms and repeatedly ringing a bell mounted on its front; and after every few steps emit a mechanical “Ah!”, as if it were speaking. The toy stood about 18 inches tall (roughly 46 cm). The gimmick of Mr. Machine was that one could not only see all of his mechanical “innards” through his clear plastic body, but one could also take the toy apart and put it back together, over and over, like a Lego toy or a jigsaw puzzle.
