Description

1974 Atlanta Flames Viceroy NHL Hockey Puck Game Used?
puck has some notations on the orange shield side, most notably what appears to be 3. 10. 74 which may translate to March 10, 1974. On that date the Flames shutout the Detroit Redwings 4-0
It's possible that this puck was caught by a fan during that game but that is only a guess
Puck is rubber crested on both sides and in excellent condition with only very minor wear shown
