Doughboy Army Hat Sweetheart Pin

Vintage WWII Doughboy style US army hat shaped pin with an eagle in the center. Interesting locket type pin. Made from pot metal (probably due to rationing). Pin on the back with hinged crossed rifles to hold a soldier's photo. It still has the original drawing of a soldier that came with it. OK condition. Wear, corrosion (?), and chips on the green paint. The eagle in the center can be rotated.
