Antique Art Nouveau Woman Stick Pin with Seed Pearls & Feather Head Piece

This is a lovely antique stick pin depicting an Art Nouveau style woman with a feather head piece and hoop earrings. It's possible that the woman was based on Native American women, but she could be based on 1920s flappers. The band on the head piece is composed of four seed pearls, possibly faux pearls. The pin looks to have once been gold-filled, but only the back looks to have some gold left. The metal appears to brass and could use a polishing. Overall, the pin is still in very good shape and was likely made around the 1910s or 1920s. Approximate Length: 2.75in
