c1970 Large Archie Henderson Tufa Cast silver Easter Blue turquoise bolo tie. Solid sterling, weight and measurements in pics. Clip on back is not sterling, tips and slide are sterling. I don‘t know much about Archie Henderson other than he was not very prolific and he he used really high grade natural American Turquoise, he even worked with some Lander Blue. He worked in both silver and gold c1970‘s.
