50s-60s Beatnik Artist Studio Copper Necklace Hammered Copper Pendant Abstract Art Modernist Jewelry Mcm Brutalist

I have owned this necklace since the 70's, and I am convinced it is a hand made artist studio piece. It reminds me of the late beatnik, early art pieces I wore myself, over a black turtleneck, back in the day. The links are easy to bend by hand, if you want them to look all the same, but I like the mish mash look of this, and always got a lot of compliments when I wore it. Some call it Brutalist, and some say it is MCM. No signature or markings. Just a great statement piece! One of a kind? You decide! 19" long, 1. 5" wide
