Gordie Howe, the Hockey Hall of Famer and 23-time NHL All-Star, celebrates his 87th birthday on March 31, 2015. The man otherwise known as "Mr. Hockey" played 32 professional seasons: 25 with the NHL's Detroit Red Wings, four with WHA's Houston Aeros, and three with the New England/Hartford Whalers. He won four Stanley Cups with Detroit. In Howe's final season, the Whalers' first in the NHL, he scored 15 goals at the age of 51. Howe holds numerous NHL records, including most regular season games played and most games played with a single team. He scored at least 20 goals in 22 consecutive seasons. In honor of Mr. Hockey, we present these rare SI photos of Gordie Howe.
