1950's Black & White 9x7's Hockey players question
 

Just wondered if anyone knows what these are and from what year?

they are on thick paper stock and about 9x7
I have these players

any info is appreciated
thanks

Verne Kaiser
Ed "Spider" mazur
Rolly McLenahan
Hugh Currie

Well, three of them, all except Mazur, played together on the 50/51 Buffalo Bisons. Mazur was there the next season. It seems to have been a Montreal farm club, and the sweaters have a Canadiens vibe, so maybe they are training camp shots of that era.

edit: but I guess that doesn't help you figure out what the set is. On that I'm clueless.
