Johnny Unitas spent the majority of his career playing for the Baltimore Colts. He was a record-setting quarterback, and the National Football League's most valuable player in 1959, 1964 and 1967. For 52 years he held the record for most consecutive games with a touchdown pass (which he set between 1956–1960), until New Orleans Saints quarterback Drew Brees broke his long standing record on October 7, 2012. Unitas was the prototype of the modern era marquee quarterback with a strong passing game, media fanfare, and widespread popularity. He has been consistently listed as one of the greatest NFL players of all time.

This Baltimore Colts mini helmet was signed in blue by Unitas and includes a JSA sticker and letter of authenticity.
