From the Mahony Photo Archives:
Eddie Mulder leading Dusty Coppage back in 1964. For ordering info contact Mahony Photos.
Update 3/2/10: We have received emails and comments that this photo was mislabeled. People have mentioned Sid Payne, Clark White, or one of the Bostroms. Anyone know for sure???
Update 3/3/10: Dan Mahony confirms it is Sid Payne chasing Mulder in the photo. Thanks to everyone who got in touch.
