#BA015 - Large 49ers Super Bowl XVI Pinback Vintage 3 3/8" diameter licensed Super Bowl 16 San Francisco 49ers pinback. San Francisco won the NFC Championship in 1981 and went on to win the Super Bowl on January 24, 1982 at the Pontiac Silverdome in Pontiac, Michigan (a suburb of Detroit). The domed stadium saved the crowd, although the 49ers got caught in bad weather and almost didn't make it to the stadium! These are old unused stock from the Super Bowl game. All left have small spotting. $1.50
