Good collection there, the Rome logo with Romulus and Remus is interesting. Although I can't remember where, when or who created the sculpture of Rome's founders, but it's the same as the one in the logo. I can understand using its likeness, but not an exact copy or sketch. But it was 1956 and it is using Roman characters. It also seems to be right at a transition between traditional and more modern art. Some of the art deco period prints are pretty cool, though.
