Those are so cool. Did you know in the mid-50s they sold Pontiac Sedan Deliveries as GMCs? I had advertising info on another computer that pooped out. searching is frustrating because so many people confuse panel trucks with sedan deliveries. You search GMC sedan delivery and you get panel trucks.
That mica paint sure works on those rolly polly bodies. My buddy who is a sign painter/air brush artist has one of these he did back in the hippy days. 100% mural on a baby blue base. It transitions from daylight with puffy clouds to a night storm sky. He may have been high when he 'dreamed' it up
. He calls it "The Cloud". This mica paint reminded me of it
