1920: The Tribune was printed on Michigan Avenue for the first time after production operations were moved there from the old building at the corner of Madison and Dearborn streets.

Print production moved to Tribune Tower in 1925, then to Freedom Center in 1982, and now continues in Schaumburg at the former Daily Herald plant.

Gale Sayers, the "Kansas Comet," is all business as he eludes the San Francisco 49ers defense on the way to a 21-yard touchdown run on Dec. 12, 1965, one of six for the afternoon. Mike Rabold, however, thinks it's a barrel of laughs as he piles up three 49er defenders. Mike Dowdle (53) and Charle Krueger (70) of San Francisco aren't laughing, though.

Sayers carried the ball just nine times from scrimmage — and scored on four of those.

Bears coach George Halas called it, “The greatest performance by one man on a football field.”

1974: “The Magic Man,” a world-premier musical comedy starring David Copperfield, then an 18-year-old magician from New Jersey, opened at First Chicago Center.

Though Roger Dettmer, the Tribune’s theater critic, gave it a scathing review, the show helped propel the career of the young illusionist.
