More like tobacco era cards (or early gum/candy cards) At first I thought they might be 1920s "Strip" cards but they look too thick a card stock for that. They remind me of the 1930s Goudey and "Gum Cards" with a sort of "comic book" art style.
I collect: Baseball, Football, Hockey, Mostly Vintage pre1980, My Homie teams - Washington/Baltimore Teams Senators (Twins, Rangers), Expos/Nationals, Redskins, Capitals, Bullets/Wizards - HOFers - Non-sport (mostly TV shows and movies).
My Trade List is very much a work in progress
