Produced from 1956 this was Marx's first foray into robot toys.
The 15 inch plastic battery operated robot was a success and was produced throughout the 1950's until Marx founded Linemar to compete with the Japanese producers.
Today this is one of the must have pieces for any complete robot collection, often the son figure is often missing as is the original packing.
This has been tested, the eyes light up however the forward/backward movement does not work.
Overall in very good condition, the lovely illustrated box has age related wear with as small split to the top.
