I have a similar helmet with the same 20th century fox scratched in the back. I wonder if that was a stamp? It looks identical. I got mine in the early 1980's out of the back of a Starlog magazine for $50 bucks. I saved up lawn mowing money all summer for it. It was shipped to me via greyhound bus. My dad had to take me to the station to pick it up. Now, back then I thought I was the cream if the crop with my helmet and Kenner Blaster LOL. Only my helmet didn't have lenses, it had little holes poked out throughout the eye area. I cut out the eye and put homemade lenses in it and still have it to this day. Allthough, I have added to my collection of helmets over the years. Not a bad find for a dallor. Oh and welcome to the FISD!
