Totally by accident today, I found it. It’s known as the Gomberg Map and it’s popular with NWO nuts. It was created by a private American citizen in 1942, and very little is known about it otherwise. It is very visually striking, and Gomberg had a penchant for lumping countries together and calling them the United States of This, and the Union of Those Republics. Apparently nothing on the map was altered, just cropped; because it still shows the “Union of Sovi–” et cetera. More information and large scans:
