Manufacturer: UNKNOWN
This is a vintage Art Deco sterling and marcasite tie clasp. It has the initials A I G or simply A G with a design between the letters on it. The clasp is marked STERLING, PAT PEND and it has a maker's mark that looks like a backwards F. The clasp measures 2-1/2 inches by 3-1/2 inches. I believe the initials could be removed by a jeweler. The clasp is in good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
