Had a look in the NY Times Archives and turned up a player named Stinson on an amateur team called Canadian Hockey Club (which was based in New York). The lettering on the sweater is open to interpretation. The first letter looks like a "C" to me except it doesn't look like the third letter which is surely a "C". Maybe it was written differently to create some kind of stylized flow. I don't think it's a "G", it lacks the thingy on the lower part of that letter. What Stinson would be doing in an Exhibits Champions set with the likes of Ruth and Dempsey is anybody's guess; there were much greater hockey players to choose from at the time. So I'm not saying it's your guy but it's the best I've got. In the second article Stinson's first name is given as "Ab". That didn't turn up anything else for me in Google but maybe someone else can run with it. Saw that in their one year of existence the CHC was 1 and 8, 12 goals scored and 46 scored against. Champions indeed.
