question: What year was the trophy, in which the 1989-90 Calgary Flames won, commissioned?
answer: 1892
context: Title: 1980–81 Calgary Flames season
  Passage: The 1980–81 Calgary Flames season was the first season in Calgary and ninth for the Flames in the National Hockey League.  The Flames moved to southern Alberta from Atlanta, Georgia, where the franchise was known as the Atlanta Flames for the first eight years of its existence.  The Flames became the third major-league team to represent the city of Calgary after the Calgary Tigers of the 1920s, and the Calgary Cowboys, which had folded in 1977.
  Title: Stanley Cup
  Passage: The Stanley Cup (French: "La Coupe Stanley" ) is the championship trophy awarded annually to the National Hockey League (NHL) playoff winner.  It is the oldest existing trophy to be awarded to a professional sports franchise, and the International Ice Hockey Federation (IIHF) considers it to be one of the "most important championships available to the sport".  Originally commissioned in 1892 as the "Dominion Hockey Challenge Cup", the trophy is named after Lord Stanley of Preston, then–Governor General of Canada, who donated it as an award to Canada's top-ranking amateur ice hockey club, which the entire Stanley family supported, with the sons and daughters playing and promoting the game.  The first Cup was awarded in 1893 to Montreal HC, and subsequent winners from 1893 to 1914 were determined by challenge games and league play.  Professional teams first became eligible to challenge for the Stanley Cup in 1906.  In 1915, the two professional ice hockey organizations, the National Hockey Association (NHA) and the Pacific Coast Hockey Association (PCHA), reached a gentlemen's agreement in which their respective champions would face each other annually for the Stanley Cup.  After a series of league mergers and folds, it was established as the "de facto" championship trophy of the NHL in 1926 and then the "de jure" NHL championship prize in 1947.
  Title: 1982–83 Calgary Flames season
  Passage: The 1982–83 Calgary Flames season was the third season in Calgary and 11th for the Flames franchise in the National Hockey League.  Despite finishing the season below .500, the Flames had their best ever finish in the division standings, placing second in the Smythe Division.  In the playoffs, Calgary was able to avenge the previous season's defeat at the hands of the Vancouver Canucks by knocking off Vancouver in four games.  In the second round, the Flames met up with their provincial rivals, the Edmonton Oilers, for the first time.  The series would not be close, as Edmonton powered past Calgary in five games, including humiliating 10–2 and 9–1 victories over the Flames.
  Title: Sandy McCarthy
  Passage: Sandy McCarthy was selected by the Calgary Flames in the third round (52nd overall) of the 1991 NHL Entry Draft.  He began playing hockey in the Georgian Bay Junior C Hockey League with the Midland Centennials and the Central Junior A Hockey League for the Hawkesbury Hawks.  As a power forward, McCarthy played for the QMJHL Laval Titan in the 1989–90 season before being drafted by the Calgary Flames.  He played one last season with the Titan.  His next stop was during the 1992–93 season for the IHL's Salt Lake Golden Eagles.  Sandy throughout his career with the Flames played the role as the enforcer, with many major fights.
  Title: 1985–86 Calgary Flames season
  Passage: The 1985–86 Calgary Flames season was the sixth season in Calgary and 14th for the Flames franchise in the National Hockey League (NHL).  It was a banner season for the Flames, who overcame a franchise record eleven game losing streak to finish 2nd in the Smythe Division and captured the franchise's first Clarence S. Campbell Bowl as Campbell Conference champions.  In doing so, they became the first Calgary team to reach the Stanley Cup Finals since the Calgary Tigers in 1923–24.  The Flames season ended at the hands of the Montreal Canadiens, who defeated Calgary in five games in the final.
  Title: 1981–82 Calgary Flames season
  Passage: The 1981–82 Calgary Flames season was the second season in Calgary and tenth for the Flames franchise in the National Hockey League.

Despite the poor record, Calgary finished in third place in the newly organized Smythe Division, earning a playoff match-up against the Vancouver Canucks.  The Flames returned to their Atlanta form, being swept out of the post-season in three straight games, as the Canucks began their run to the Stanley Cup Finals.
  Title: 1988–89 Calgary Flames season
