Business envelope for the NHL team Chicago Black Hawks. Note that the name of the team is two words: Black Hawks. Prior to the 1986–87 season, while going through the team's records, someone discovered the team's original NHL contract and found that the team's name was printed as a compound word ("Blackhawks") as opposed to two separate words ("Black Hawks"), which was the way most sources had been printing it for 60 years and as the team had always officially listed it. The name officially became "Chicago Blackhawks" from that point on.
