I like it when people toss a decent theory out there because it seems to get the investigative part of people going. Most of the time, especially with century + old cards, there's very limited information. Tossing ideas and theories out there may help us stumble upon the right answer.
It reminds me of the T202 Joe Jackson sliding thread. Now, I know many still may not believe it's him, but I sure am convinced; thanks to some very good and thorough researching by various board members, along with a great theory by the OP.
I can't say much about this card, I don't know enough about these cards to comment, but I love these types of threads
Sincerely, Clayton
