Seeking help attempting to identify cards
Hello, looking for help trying to identify these cards. I know the 1929 Parker Brothers makes a series of blue backs with a face in the center and the 1935 Whitman's also have the blue back w/face, but I have never seen a series that has a puzzle piece back like these. They look authentic and smell like old card stock. 

Any help would be appreciated. Thanks in advance!
