This is a vintage Cock Rooster Chickens Fighting b2 old enamel pin. Size 1" x 9/16".  Pin has on back a pin post and  push on clasp to hold it in place . I purchased a large collection of vintage pins from an ill man unable to do business anymore. I did some research on these items and found that most of them were manufactured before 1982.   I am constantly acquiring vintage items. Keep JIMGEMZ1 bookmarked. You will not be sorry. I would consider it a privilege to do business with you. I value the items I sell.
