Small world! The pic of small town with 60's cars is of montour falls new york, looking towards the falls, cannot pronounce the name, never could. Been there a million times. Not to far from watkins glen, nascar road course.
This one had me confused for a moment as that's a '57 Olds coming out of the oven & a Pontiac over to the right. I thought all the divisions had their own plants in those days, but the internet says this is the Oshawa Ontario factory and it built most of the GM brands at the same time.
