Vintage Airline Playing Card Decks - Worth Collecting?

So, I've recently stumbled onto a few airline-branded playing card decks from the 70s and 80s. They were just sitting in a box in my grandparents' attic. Didn't even know they had these! There's a Pan Am deck, a couple from TWA, and a really cool one from Braniff.

I'm curious if anyone else collects these and what you think about their value or collectibility? Honestly, I think they're pretty neat, and they seem to be in great condition. The designs are super retro, and they feel like a snapshot of airline history. Not sure if I should just hold onto them or if there's a market for these somewhere.

Any insights would be awesome! Do you guys trade these or display them somehow? Would love to hear your thoughts or see pics if anyone else has a similar collection.

I've got a few of those decks too! Found mine at a flea market a while back. The Pan Am ones seem to be pretty popular among collectors. Some people pay decent money for them, especially if they're in good shape. I'd say hold onto them for now. You never know, they might increase in value. Plus, they're just cool to have around. Do you plan on displaying them or keeping them tucked away?

I've got a few vintage decks myself, mostly picked up at estate sales. They're a cool piece of airline history. The Pan Am ones usually get a lot of attention, probably because of the brand's iconic status. I'd say hang onto them if you like them, but there's definitely a market for these on sites like eBay. Just make sure they're in good condition. I display mine in a small shadow box on the wall. Gives them a nice frame and keeps them safe. Have you checked online to see what similar decks are going for?
