A canologist is a beer can collector.
If you are one, you might want to join the Beer Can Collectors of America.
Despite the name, the Beer Can Collectors of America is an international organization and it concerns itself with more than just beer cans.
Four thousand active members in over 45 different countries collect what they call “breweriana”, just about everything pertaining to beer advertising and packaging, including “bottles, cans, coasters, crowns, glasses, labels, lights, mats, openers, posters, signs, steins, tap knobs, etc.”
