I had this goal as a kid back in the 80's to collect all of these silly little things, so much so that I got that poster and studiously checked off everyone that I collected. However, it was never meant to be. Just yesterday, though, I was driving around and for some reason I remembered these things and the great mystery from the 80's - the little plastic guy that wasn't on the poster. I couldn't remember what the collection was called so I had to look it up. I found this site and quickly determined that the toy that stuck in my head for so long was indeed a "rare" Black Hole Sunshine. I had obviously gotten rid of all of my other M.U.S.C.L.E .men, but even back then I had the foresight to keep this one. I searched my attic and found it. Now I just don't know what to do with it. As I've been a collector of weird things my entire life, I managed to keep him in pretty good condition.
Any suggestions? I thought I might find a whole stash of other M.U.S.C.L.E. men with him, but alas this was the only one I kept.
