c. 1952 Toronto Maple Leafs (baseball) issue
 

Can anybody tell me what these are? They have postcard backs, facsimile autographs and include one player (Dobernic) who only played for the team for a couple months in 1952 ...

neat
 

I always like obscure stuff and those are neat looking to boot. Kind of like the Deckle Edges of the 60's-70's. Maybe those were sold or given away in the souvenir shop at the ballpark... or something like that? :)
