Just an update on my research, I read Fitzgerald's handwritten ledger yesterday, hoping to find some solid info on t206s, to no avail. I did, however, find his September 1905 entry regarding his stamp collecting, which he described as "a passionate stamp collection" as well as his love for baseball (and other sports). He played several positions of baseball and his father was a fan as well. For instance, an August 1906 entry reads, "...father used to drink too much and then play baseball in the backyard." It's entirely possible his father was the one who supplied the cards from tobacco products and young Fitz collected them, as he did his stamps.
