These are part of a 4 dual panel, 8 card set. Each panel has a perforation down the middle plus they are die cut around the bust area to the top of their head and were meant to be bent in half.
Offered through label redemption these cards are Canadian as they say Litho. In Canada. I think the correct year is 1933 but we agreed on circa 1930.
There is an American set which is much larger, I think they have 12 dual panels, or 16 cards in the set. No hockey tho!
