I didn't check the entire list in the OP yet, but I did notice Chance should be the bat off pose, not yellow portrait.

This is additional player information to add to what is in the OP that is important to dating the set.

Bridwell-Boston Nat’l---July 22, 1911 Traded by New York to Boston Nat’l
Davis-Cleveland---October 1911 named Cleveland manager
Paskert-Philadelphia Nat’l---November 12, 1910 Traded to Philadelphia Nat’l
Street-NY Amer---February 17, 1912 Traded to New York from Washington
Young-Boston Nat’l---Signed contract with Boston Nat'l Feb 1, 1912 - retired May 24, 1912

Every subjects team designation in the T215-1 set is where they were in the first few months of 1912 with the exception of two. The two are Howard-Chicago Nat'l and Manning-New York Nat'l. Howard did not play for Chicago after 1909 and Manning did not play for New York after 1910.

There are players that have no statistics with their designated team in 1912 but were with them at the beginning of the year.

Conroy-Washington---Retired/Cut prior to the season in March 1912
Dougherty-Chicago Amer---Retired in late February 1912 prior to the season.
Elberfeld-Washington---Retired/Cut prior to the season in March 1912


I'll add more regarding the Pirate set later.
