Thanks for the reply, Freak.
Yes, it shocked the hell out of me, as well! Anyone know which Lucas biography?
The photo on the IndyCast page doesn't look like a 2-page spread so it might have been published elsewhere and the Lucas bio must have a sharper picture.
The shot where Shorty is crossing the plank was reversed so I've flipped it to show how the scene would've most likely played out. Here they are in all their glory (images courtesy of 'Trivia Guru Pat' on the IndyCast Flicker page)
. AWESOME find!
