WAC Army Air Corps Heart Pin on Card

Original WWII WAC and Army Air Corps heart pin on card. Interesting sweetheart piece. Looks to be made of an early plastic (and maybe wood?) material. 'Made of non essential war material' made by Galawood-Roth. These type of pins were produced and sold cheaply. The materials were generally not the best quality and the craftsmanship leaves a bit to be desired. There is residue (glue?) on the hearts and the brown color has come off in a spot on the back. The corner of the card has a crease and is close to ripping off.
