There are several barf bags collections in the world but the one i’d like to share with you is a “Kelly’s World of Airsickness Bags“. I would nominate his collection for the most comprehensive barf bag collection in the world, although he is not a Guinness Record holder for such a collection yet. More than 6000 bags, about 1500 airlines. His collection helped me a lot to systematize and represent my collection here. Thank you, Bruce!
I have also dealt with other fellow collectors:
