It was a neat addition to the classroom, and especially fun whenever a former student would stop by with one from an exotic airline.
He was well liked :)
Wonder if I still have any in my travel memorabilia I have going back many decades.
Source: have flown on older retrofitted planes without barf bags.
Was waiting at a drive through coffee recently with the dog in the front seat. She needed to vomit right as I was about to pull up to the window. Just happened to find a small paper bag from lunch, or something, and was able to get everything cleanly in the bag! A dog snout fits more cleanly into a bag than human I think, but have never needed to use one myself.
Unless an airline would use your design, yours would be just a “barf bag” and I doubt colletors would be interested.
Find a barf bag supplier, have the Pan Am logo printed on them, stick them on Poshmark, and let the easy dough roll in.
