In 1984 Star Company released a Carl Yastrzemski tribute set in vacuccum sealed bags. 500 of them were autographed and numbered. That would make these cards the first card company released autographed cards in hobby history and also the first numbered cards.
Now these were not pack released, as Star didn't do packs, and I'm not sure of their distribution dynamics, and that knowledge may be lost to time, but before these, no modern card company had ever distributed autographs or put numbers on them, though in this case Yaz also put the numbers, so in a sense it's also the first player inscribed card as well lol
And yes of course the 1990 Upper Deck Reggie Jackson is still the first pack released in history.
