Jared and Jon have correctly described the scenario regarding ATC's divesture in 1911. The following pictures are simply intended to illustrate this scenario, as reflected
by the T206 cards....circa 1910 - 1911.
This PIEDMONT pack of mine is the American Tobacco Co. Factory #25, Richmond, VA version (circa 1910). The PIEDMONT Liggett & Myers version (Factory #42) of the
same pack begins in the early months of 1911. Correspondingly, the PIEDMONT advertising on T206's changed to Factory #42 to reflect the anticipated break-up of ATC.
