[Michlib-l] Friday mystery

Hello, I found a handful of these little guys in the back of a supply cabinet. Can you tell me what they are? The box they were in was labeled “place card holders,” but I’m not aware Demco produced tableware. [Best guess here is maybe holding a catalog card, while typing a duplicate.] Thank you, Meredith --- Meredith Sommers Library manager Bayliss Public Library, a Superior District Library Sault Ste.
