My curiosity concerning the Doolan/Doolin confusion started with trying to establish what happened and why there are two 1908-09 Rose Company postcards of the same person. The Doolin was published in the initial issuance (1908) the Doolan sometime later. Why the change? Why issue another card?
In trying to analyze this unusual case I find the 1909 T206 checklist with the same problem. So being there are a million or so T206 collectors perhaps.......
The baseball ref states: Doolin - SABR spells it: Doolan - Wiki=Doolin – Rose Co. makes costly change of printing another card to go from Doolin to Doolan. T206 has both.
There must be some logical conclusion to this dilemma.
