Was wondering there were any other back back "versions" for T200 and T201 sets.From the Library of Congress site I was able to find two different backs (Factory information) for each set.For the T200 "Factory No. 25 Second District of VA" and "Factory No. 42 Fourth District of N.C.":Of the 13 card scans, only 2 had the Factory 42 back (Philadelphia Athletics and Washington Nationals) For the T201 the is a Factory No. 30 and Factory No. 649 Does anyone know if each Front can be found with both Factory Back versions?Thanks,ChiSoxFan
