Here's the spaceman doing what he did best: Posing for photos with tourists. I'd guess this one is from the late 1950s. Jimmy here is wiping the fruit punch stains off his mouth before posing for Dad's camera. (I believe these photos all came from an eBay auction I stumbled across years ago.)
Man, I'd give my eye teeth for a replica of this outfit to use as a Halloween costume. And maybe a Space Girl outfit for my girlfriend too. Know anyone who sews costumes from scratch? And does anyone have a spare "bubble helmet" or two sitting in their garage?
This last shot is clearly from the late 1960s, with the Astro Jets whirling around in the background. The costumes have been greatly simplified by this point, with the exception of the easy-to-damage antenna atop the helmets.
