A handwritten note on the other side of the full version of this photo identifies one of the men as "Eugene E. Gates, Sr.," and tells the viewer to "look for man with beard, dot on shirt, in centre (back) of [the group in the] photo."

I've circled Gates here to show where he's standing within the group. The mark that indicates his location is more of a smudge than a dot.

For a wider view of the group, see a cropped version of the photo. For more information, see the full version of the photo.
