Well, they made a series about the civil war and there were two sides to depict. Considering many others Longstreet is a pretty good choice - moderate, no fireeater, solid reputation, post-war career (Liberty Place, aye?) etc etc. Other Confederates in that series that I quickly found are Joe Johnston, Raphael Semmes, Jefferson Davis, Robert E. Lee and Stand Watie.
As said Liberia creates lots of series and many of them about parts of U.S. history. But also coins about German banknotes, about stuff like golden weddings and, being really good, about Star Trek.
