Was able to match this photo with one in a Princeton archive that had each player identified:
Standing in back:
Wheeler,
Holly, Blake
Sitting in middle row:
Brown, Balliett,
Trenchard, King,
Taylor,
Lea
Front Row:
Ward,
Morse
Mayo players in bold.
It is generally believed that the Mayo set was created from player images taken from 1893 team photos. Photo images were touched up to remove surrounding players and uniforms were redrawn/sketched as needed. You can see the similarity when comparing the poses in this team photo with the Mayo cards themselves.
