1976 Topps Rack Packs.
One of my uncle's bought me a bunch of rack packs when I was over my grandmothers house. I remember being disappointed they were 76's, because I knew the 77's were out by then, and Reggie wasn't in a Yankee uniform in the 76 set. I don't think I got any Yankees I recognized in those packs.
I think I got a Bobby Bonds, and I was like "who is that?". My uncles told me, he was pretty good, but he's not on the Yankees anymore....but they did get Mickey Rivers for him. I was like "great, but why is Mickey in an Angels uniform?" LOL!
Maybe they were out late in 77 because Topps was behind schedule airbrushing a Yankees cap onto Reggies card.
Got my 77's in due time, and was ecstatic with that design. I think I held an irrational dislike of the 76 set through most of my childhood and even part of my adulthood. I trace it all the way back to that day.
