Hey Scott
A lot of work there guy, thanks for the time and effort you put into this research.....great stuff.
Years ago, I did a comparison of the E90-1's 1910 (last) series subjects with the 1909 RAMLY. There is no doubt that this E90-1 last series cards were
short-printed. And a good number of them are Boston-based and Cincinnati players (Graham, Ritchey, Stahl, Bill Sweeney, and Karger, Lobert, McLean,
Mitchell, respectively).
I arrived at this theory that a possible conflict with the 1909 RAMLY set may have resulted, since American Caramel did not include these guys in their
1st and 2nd series issued in 1908 - 1909.
And, of course (in my opinion the toughest) Tris Speaker was issued in the short-printed 1910 series since his first full season in the Major's was 1909.
Any thoughts on this hypotheses ?
