I believe the earliest version of The Laughing Robot went on sale late 1969. The toy was manufactured by Yonezawa but branded and sold by two different companies. The Waco branded ‘The Laughing Robot’ and the F.J. Strauss Co. Inc. branded (Straco) ‘The Hysterical Robot – Happy Harry’. Later versions of The Hysterical Harry came with an additional battery compartment in the rear shoulder area (likely for the speaker) to improve the toy’s electronic reliability.
