It doesn't take a psychiatrist to realise that the urge to collect toys comes from childhood, and for us who are floating dubiously around the 35-45 year old mark, there were many toy manufacturers in the late 70's/early 80's. The most famous of these were of course Hasbro who created the Transformers and Mattel, the Masters (HA!) of the He-Man series of toys.
However, one of the the most famous, and cross media, companies was probably Kenner.
