As I was always curious about this photo maybe someone else is as well. Here’s some background from Wikipedia (Maurice Richard’s entry):
On April 8, 1952, Richard scored one of the most famous goals of all time, described variously as “the greatest in the history of the game” and “most beautiful in the history of the world.” As blood dripped down his face after an earlier injury that saw him suffer a concussion, he scored the series-winning goal of the 1952 Stanley Cup Semifinals. Richard had left the game, but returned to the bench in the third period, wearing a bandage. Richard, although somewhat dazed, jumped off the bench and drove to the net to score past a surprised Sugar Jim Henry, the Boston Bruins’ goaltender.
