That's a really cool find.
Even though Jim and I are old hats at this now, when BTAS came out, we were still kids/early teens. So, we wouldn't have this. But there may be some people I can reach out to. They probably received it in '92, though. Either in the weeks just prior to the show airing, or during upfront season, which is usually in the spring. Bear with me. This may take a spell.
