All of the toy soldiers I've featured to date have been "vintage" plastics, from the 1950s and early '60s. These guys are relatively new. Sometime in the '90s, I believe, an outfit called Barzso Playsets, Inc. started manufacturing all-new playsets and figures in the Marx tradition - aimed not at kids but at collectors. One of those collectors was Cap'n Bob Napier, who gifted me, way back when, with this set of pioneers. Barzso is still making this stuff, and their latest release appears to be a Roman Colosseum, complete with gladiators. You can see that HERE.
