Baltimore has won two Super Bowls - won in 1971 with the Colts, and in 2001 with the Ravens.
The Baltimore Sun looks at the changes in the game since those early years, when the game finished in sunshine.
Bill Curry, who played in three of the first five games, found out the difference over the years.
In 1967, tickets for the first NFL-AFL championship game, as it was then called, cost $12. Four years later, when the Colts defeated the Dallas Cowboys in Super Bowl V, seats were $15.
"This year, I called the NFL and asked if former players could buy tickets," Curry said. Told the cost would be $900, he asked, "That's for two tickets, right?"
Wrong. Curry was stunned.
"I decided not to buy them," he said.
