Anyone else collect vintage airline uniform buttons?

So, I stumbled upon a small collection of airline uniform buttons from the 60s and 70s at a garage sale last weekend. Didn't even know this was a thing, but now I'm kind of hooked! Got some from airlines like Pan Am, TWA, and even a couple from Eastern Airlines. They're surprisingly detailed, with little logos and intricate designs. I'm curious if anyone else collects these or knows more about them?

Are certain airlines more sought after? And how do you even display something like this? I'm thinking of putting them in a shadow box or something. Would love to hear if any of you have tips or stories about collecting these. Maybe I'm just late to the game here, but it feels like a hidden gem in the world of aviation memorabilia!

I don't collect them myself, but I know a few folks who are into that. Pan Am buttons are definitely popular, probably because of the nostalgia and iconic status. Displaying them in a shadow box sounds cool and would keep them safe too. Maybe even add some airline-themed fabric as a backdrop for a bit of flair. Do you have any buttons from airlines that don't exist anymore? Those might be pretty rare and sought after by collectors!
