I've collected MUSCLES since I was a kid in Michigan and for sure opened Class A figures from 4 packs that I bought in Michigan. MUSCLE made kind of a comeback at my elementary school in 1993 when I was in 5th grade. I remember that we were buying MUSCLES from Meijer and that all of the CLASS A figures I bought came from buying figures at this time from that store. So, As were for sure opened in the USA in Michigan.
Also, that Purple Arch lot looked shady as hell-which is why I didn't bid on it. The guy clearly knows that it is valuable but puts it into a lot with a bunch of random stuff, junk MUSCLE, and an expensive series 3 MIMP? I would not expect this figure to ever arrive. I expect the low price might have something to do with more serious collectors not wanting to get involved with a potentially scam situation. So, for whoever bought it if it shows up they got a really nice but risky deal! LOL.
