This amazing silver Modernist bracelet is unsigned but most likely made by the Japanese modernist Toyo Koki c. 1946-48. The clasp is marked "Silver" and "<CPO>. "CPO" is an acronym for "Central Purchasing Office," an organization that served US Military Exchanges operating on American bases in Japan post WWII. A dramatic and interesting piece.
Details.....The bracelet measures 7" long. Each link measures 1.07" by 0.46" wide. In Excellent Vintage condition. You should expect some wear on all vintage and antique jewels.
