Lot of old thermos bottle cups and camping cups... these are cute little things, not at all like the giant cups they put on insulated bottles these days!
Two of these are red bakelite or another early plastic type material. These are both 3" in diameter, made to fit Aladdin bottles. They are 2" and 2 1/4" tall.
The aluminum camp cups have wire handles, and are dirty from use over a fire, and other pitfalls of campfire cooking and washing up. They're water tight, though they do have dings and dents.
