Warren Hats of Rochester, New York was offering a free Stetson Hat to any Rochester Americans player who would score 3 goals, (hence the Hat-trick) during a game in the 1959-60 season.

Mike Harris, proprietor of Warren Hats is seen here holding a Stetson Hat box.

Many stories have been told of hat shops giving away a free hat for scoring 3 goals. This is one of them.
