I just wanted to make an update as I've been able to positively identify the player on the E270 Tin Top incorrectly identified as "Byrne" for Pittsburgh.
There was a thread recently where there was a link to the VintageBall.com website about postcards and the same image was again misidentified as Bobby Byrne, while with St. Louis NL on his 1908-09 Rose Co. postcard.

This really changed my search as I had anticpating the image being from much later, 1912-13, when the Tin Tops were being produced--obviously seeing the image in a 1908-09 set indicated an earlier photograph and then it didn't take too long to realize it was actually an image of
James Joseph Byrnes who only played in the majors w/ the 1906 Philadelphia Athletics. I'm sure when I initially started looking I had eliminated him as his Major League career was so much earlier than I was thinking. The funny part is that that exact same image was used to produce another card of Byrnes, while with the 1910 Tacoma NWL--his 1910 T212-2 Obak...
So, much like Colgan's did with their E254 Ryan goof, in chich they used a 1903 Carl Horner image of Jimmy Ryan on their 1910 card attempting to depict Jack "Gulfport" Ryan. Here they used a 1906 Horner image of Byrnes w/ Phila AL in their attempt to depict Byrne on a 1912-13 set.
Anyways, it feels good to put this one to bed.
