This product is a mixed lot of vintage 1950's Fender guitar picks, Herco brand + unknown black pick maker and colorful celluloid curled picks made of durable celluloid, I believe all may or may not be celluloid material. These classic guitar picks are perfect for any musician looking to add some authentic vintage flair to their instrument.  Wear to lettering, multicolor pick hasn't a signature. Estate purchase.  Message with questions.
