Wow Jay, thanks for showing your near full run on the 1887 NL studio proofs. Here is the only team not yet shown (not mine).
Williamson-Chicago
As for the Detroit players in my OP . . .
Brouthers
Richardson
Rowe
Weidman
Barry, Ned Hanlon has a near identical "bat at side" pose as Rowe, easy to mistake them.
I'll post more later, far more 19th century Detroit material to share (outside of Studio Proofs).
