Wonderful and unusual little vintage brooch! It is shaped like an old time radio. Inside the little window you can paste your small photos. The dial turns and spins the disc to reveal the photo you want to display in the little window, while the rest of the photos on the wheel become hidden. The dial has a red plastic cabochon. Signed "PAT PEND" on the back. I think this may have been a promotional item for a radio show, as I have another in my personal collection that had the headshot photos of 1940s or 50s era stars. This one does not have photos. Gold tone metal. Measures approx 1 5/8" long. It's in good preowned condition with normal age wear, some darkened patina. Ships fast! ELEJ81788JD6H5R
