There are some great vintage baseball channels out there.
BaseballCollector, ChrisFromMissouri, MidLifeCards, CollectorInvestorDealer, BlueJacket66, ACollectorsDream, DeadGuyCardboard, SammyThunder, SouthernCollector, VintageOddballCards, and The Mangini Collection to name a few!
I actually just started a channel myself and talk about PreWar and Postwar baseball cards along with PreWar track & field cards.
