Alox, Heaton, and Cairo Marbles

Alox (1920s), Heaton (1946-1960s), and Cairo (1948-1953) are three relatively small vintage marble companies that produced swirls and opaques for games and five and dime stores. Most of their marbles are hard to identify. Some look like Ravenswoods and are sometimes mistakenly sold as such and vice versa.
