Vintage Navajo Copper Cuff Bracelet signed by an artist with the initial "J"

Pre-owned by a family member not sure how long it has been stored in a jewelry box in a smoke-free home. No damage, there is the letter J engraved on the inside. My Aunt enjoyed visiting the Navajo Reservations and purchased jewelry from local artists. I take close-up pictures of the items so the details are clearly visible. It can make items look bigger, so please review the measurements in the photos Please view the photos for a better description.  Stored in a smoke-free home. **I consider most offers on all items**
