Script error The Little Brown Stein is a rivalry trophy awarded to the winner of the college football game between the University of Idaho Vandals and University of Montana Grizzlies. The trophy is, as the name implies, a large stein mug with the results of all the games between the two painted on.
Idaho and Montana first met in football Template:Years or months ago in 1903 and have played 84 times; the stein was introduced Template:Years or months ago in 1938, at the 25th meeting. Idaho has dominated the overall series (.659), which also includes two Division I-AA playoff wins at home in the 1980s. Montana has had the upper hand since 1991, winning nine of the last eleven. While Idaho was in Division I-A (FBS), from 1996 through 2017, the teams met only five times, with Montana winning the last four.
Both were members of the old Pacific Coast Conference (the forerunner of today's Pac-12); Montana departed after the 1949 season, and the PCC disbanded in the summer of 1959. In most years, the loser of the game was last in the PCC standings.
The universities were charter members of the Big Sky Conference in 1963, (although Idaho remained an independent in football until 1965) and their final season as conference opponents was in 1995. While Montana has been in the Big Sky since its inception, Idaho has changed its conference affiliation no fewer than five times since 1995:
- Idaho moved to the Big West for all sports in 1996, returning to Division I-A after 18 years in I-AA.
- After the 2000 season, the Big West dropped football. Idaho became a football-only member of the Sun Belt Conference in 2001 while remaining a full Big West member.
- Idaho joined the WAC for all sports in 2005 as part of a major NCAA conference realignment.
- After the WAC experienced a near-complete membership turnover in the early 2010s, it dropped football after the 2012 season. Idaho football was an FBS independent for one season in 2013.
- Idaho returned to the Big Sky in 2014 except for football, which rejoined the Sun Belt.
- Idaho dropped back to FCS in 2018 and resumed football membership in the Big Sky.
- Years not played: 1904–13, 1918, 1943–44, 1954, 1963–64, 1996–98, 2004–17
Since 1945; Idaho led the first 29 meetings (through 1942) at .707).
