T218's vs. T219's vs. C52's

[Exhibitman]

Not a Tolstoi back. Perhaps my post was confusing. What I am trying to get my arms around is the idea that the 49 cards listed above are "T218 series 2 subjects." I don't think that's an accurate characterization. The green bg Johnson would seem to break that rule since it can be found in either series 1 or series 2 back format. I also have series 1 backs of Gans, Gardiner, M. Sullivan and Walsh, all of which are on the series 2 list, which would seem to be enough exceptions to the rule to destroy the rule.
