This is it. Just the mirror you have been searching for. Circa 1930s cast plaster foliate and shell design with its original antique and distress mirror glass. I believe this type of plaster mirror was originally “plastered” into the wall and, as you can see from the photos, the mirror glass is plastered into the frame. Done in the style of Serge Roche of palm or acanthus foliage and shell designs. Originally white but has been given a bronzed paint effect. I’d call this Art Deco or Hollywood Regency. You should call it yours!
