Yeah ... from the 00's to the 30's the glass marble companies were doing their best to appeal to boys brought up on the ideal of stone marbles.
P.s., I refer to this ad a lot to remind myself of Master's names and original style designs, because Master's later production became so indistinct, and because collectors keep trying to fit Master marbles into pigeon holes that the anything-goes production of later years don't really fit into. This ad is my touchstone.
