Somewhere on him it says Mego and he stands 12" high. Seems like every kid I knew back in the 70s coveted one of these.
There was also a Remco Spider-Man toy which came out around the same time. Its arms and legs didn't move so neither I nor any of my friends wanted that one. I remember its hand was in a fixed upward web-shooting position and there was a retractable web (string with a hook on it) which would hoist him upwards. I kind of wish I had him now.
