They appear to be complete decks, I'm not really sure. The decks are really old and some are for games I've never heard of. My parents found them on top of a closet when they were remodeling. There is a deck or two for charades, Millbourne's, fish, authors and a bunch of others.
I didn't find any dates on them. That being said, some of the decks, Charades for instance, are so politically INCORRECT, and the pictures on them are clearly from the early part of the last century. Another one of the decks has names on it such as Stella Steno, etc. depicting people in clothing clearly from the '20s and '30s.
