These 60mm GIs (from the early '50s, I believe) are probably among the first toy soldiers manufactured by the Marx company, and possibly some of the earliest soft plastic toy soldiers made in America. The only other Marx army men that might date from this period stood about an inch tall and were sort of cartoonish. I'll post some of those little suckers on some Saturday to come.
These 60mm guys are slightly less realistic than the more common 54mm figures Marx issued a short time later. I posted a few of those guys HERE, and there will be more to come.
More soft plastic warriors HERE.
