Nose tackle Michael Carter was part of that Super Bowl lightning that struck back to back for his San Francisco 49ers during their 1988 and 1989 seasons. Football shaped diamonds charm the top of this ring, while one side celebrates their “Back to Back” and “55-10” victory over the Broncos, the other side contains “Carter” and “17-2”. “10K Jostens” is stamped on inside. Size 16.
