Prison ring c. late "Hazel" This is a fantastic example of these types of rings. The front of the ring is an inch long. The man who made this did not want you to miss his sweetheart Hazel. Laminated celluloid and Bakelite.
Prison ring c. Celluloid shank with Bakelite scrap used for checkered effect with confetti lucite front. The picture is of a midshipman, "Reginald," in the Royal Navy during WW II. I purchased this ring from a man in the UK.
