Badlands Passport

So I wasn’t able to get VIP but I’m now obsessing over wanting one of these fing passports lmfao. i’ve seen people say that they show up every once in a while online, but i was curious how high/low the chance of me finding one would be. does anyone have an idea or have a suggestion on the best places to be looking for them? i’d love to collect all 3 eventually if possible. i know you can get a replica made on etsy but i would really love an authentic one if i can find it. thanks!!!
