The photos and newspaper accounts are only part of the supporting evidence for both cards. IMHO, the smoking gun is Joe Jackson's unique right-ankle wrap. It was widely reported in contemporary sources that Jackson injured his ankle in spring training and multiple 1911 photos show Jackson wearing the white ankle wrap through at least the Addie Joss benefit game on July 24, 1911.
Collectively, the evidence supports Jackson appearing in the action photos of both the Tannehill/Lord and Milan/McBride T202 cards. Here is a quick summary:
