22 inches silver long flat necklace double sided

This is a great 22 inch long flat silver colored flat necklace double-sided with a different print on each side it does appear to be sterling silver I also used sterling silver cleaner on it which did make it shine more however because it's vintage there doesn't seem to be any stamp or it has worn away I cannot guarantee it's silver although it does appear to be so and that is reflected in the price there is no damage and no visible signs of wear just age from normal vintage conditions
