Vintage Cards Old Maid? Strange Pictures!

Description

Here is a collection of old cards with some very interesting artwork.  The cards are numbered in pairs, so possibly from an Old Maid set, but who knows.  The cards are in poor shape with some being barely there and others missing.  The backs are a light blue color.  Can anyone use these?  Vintage Cards Old Maid?
