Maybe a museum, but at the end of the day, it’s a UTEP made banner, not a trophy made by the NCAA.Some museum might take interest in the 1966 team given the history made by the team (they made a movie about it, after all).
But it's just a banner. I don't know why anybody would plop that kind of money for a mere banner. UTEP can and will just have a new one made.
Do we even know if it’s a 58 year old banner and that it hasn’t been replaced several times?
