It's a clip from the memorable 1970 game where the Giants came from behind and won 23-20 ... a game where Pete Gogolak kicked a then-NFL record 54-yard FG only to have it eclipsed, later in the day ironically enough, by Tom Dempsey who kicked that 63-yarder for the Saints against the Lions.
Frank Glieber and Frank Gifford are calling the PbP.
I have the DVD on this game (a partial) which consists of the third and most of the fourth quarters.
Peace!
