At halftime of a 1958 game, a 49ers fan went out on the field at Kezar Stadium to confront Bears coach George Halas, who he thought was trying to intimidate the officials. (Not that Papa Bear would ever do anything like that.) The result was this memorable photo of Halas’ son Mugsy springing to the rescue — while George (the gent to the right in the hat and sunglasses) looked on approvingly. I particularly love the cigarette dangling from Junior’s lips.
