I'm guessing those PJs came from Sears or JcPenney, but I can't find a better shot of them anywhere on the ol' internet. But the Turbo Cycle? No problem.
Sadly, my original Secret Wars toys are some of the ones I parted ways with in college when I first discovered eBay. I'm sure the money I got for those toys went to a good cause like a ticket to see Counting Crows or a few cases of Rhinelander.
More of this to come. Maybe.
