Cool little novelty set , robusmc .
Perhaps from a : novelty shop , carnival/fair booth/game o'skill/chance (including 'prize-items') .
Looks as if they are lithographed metal , perhaps to imitate 'tintype' photos .
My guess is from the 1920's thru 1940's & U.S.A. manufacture .
Any small/tiny identifying/additional marks on your items ?
