I recently acquired this 1907 RPPC of Henry "Hank" LaBelle who played for the 1907 Newark Sailors team.

I found this 1907 composite of the 1907 Eastern League and the my LaBelle is an exact photo match. The photos of were by H.C. Weasner a photographer out of Buffalo, NY who was a contemporary of and reminiscent of Carl Horner.

Here is a close up of the Newark and Toronto teams.

I know another member here has a postcard like mine of Weidensaul from the Toronto team, hopefully he'll post it. Ironically it is just to the left of the LaBelle in the composite who is just left of the Newark manager.
These are gorgeous cards. Does anyone else own or ever seen other examples? It makes sense that if two exist from different teams that postcards for the entire league might have been made. Is this a known set?
