After speaking with several collectors in regards to this I believe that there is enough evidence to support a new variation for the T205 set. The George Graham Rustlers card can be found with a "Blue Signature" on AB, BL, Cycle, Drum, and PB. All of these backs combined only make up about 15-20% of the total known copies out there. All other backs are found with the typical black signatures, including all the "Cubs" variations even with the PB back. I believe this is enough evidence to support another new variation to the set. The cards should only carry the premium attached to the backs, but only the market and collectors will determine that in the long run.

Please feel free to comment and keep things civil. Please keep the debate on the card in hand and not some WUNC card or other set not similar to this one please.
