This is a real treasure courtesy of John Josephson. It's the start of the Main at Thunder Bay, in a special show, early '70's. John wasn't sure what year but you'll see Ron Carlson leading (disappearing at left of frame), blue car is Bob Hop, red 14 is Bill Dollansky, black 3 is Dennis Olson, red 4 is Al Jacobson, white with blue nose is Lyn McIntosh, 12 is Ron Larson, 87 with L.F. up is "Haircut", 63 is Jerry Richert, white 4 is Don Mack, black 31 is Stevenson, and you can just see Kettering's white roll cage at the far right of the frame.
