And given the fella in the bottom middle picture seems to be brandishing one of the Sandman guns from Logan's Run it made me wonder if the photo shoot had been enhanced by a movie prop collector, someone such as William Malone, a well documented collector of SF memorabilia and also the director of Titan Find? Not sure if anyone can spill a little more light on this company and their relationship with Malone but if he was looking for someone to make him some looky-likey 2001 helmets a few years later, you would be hard pressed to find a more capable studio.
As a final thought, given that it was actually this helmet...
...I was investigating. I still feel like I've seen it in a Don Post advert but then I also think the creature inside looks a lot like this;
..so maybe that's influencing my thoughts. It's worth noting that Jukebox was an original design from the 1985 catalogue, and yes that's the same year that Titan Find came out. Coincidence?
Anyway, while you mull them thoughts over why don't you go over to The Blood Curdling Blog of Monster Masks which can be found by knocking on this door; http://monstermasks.blogspot.co.uk/
