Vintage Dark Blue Hinge Bangle Bracelet With Safety Chain Signed

For your consideration is a vintage hinged bangle bracelet. It features a deep royal blue enamel and polished gold tone bangle bracelet with a safety chain. It’s hinged which allows ease when putting it on or removing it. There’s a marker’s mark inside but I don’t recognize it. It’s a great chic classic piece. Please refer to the photos as they’re part of the description. Very good preowned vintage condition. Size: 6-3/4” inner circumference 5/8” wide
