According to Wikipedia, the Lombardi trophy stays with the football team, not the city. However, Baltimore sued and won to retain it. But, where is it kept? Is it on display at (what as rightfully called) Raven Stadium? …Is it locked in a safe?
It’s at the Maryland Sports Hall of Fame at Camden Yards.
“As the official archives of the Baltimore Colts, Sports Legends Museum uniquely chronicles the love affair between the city and its team, using photographs, fans’ stories, marching band uniforms, and authentic game memorabilia, including the team’s Super Bowl V trophy.”
