From the late 1960's, worn by my brother to Woodstock. Has 2 layers to the pendant. The back shield appear to be a plastic material, plated in distressed silver. The knight is a metal also plated in distressed silver, chrome. Definitely has a dark patina. The chain is large links, shows some wear on the chain and the shield, 14" long. Beautiful on, could use for festival wear, gift for the guy in your life or for you. All items are from personal collection and may show wear.
