I like the first one with the old flathead. Was '54 the last year Ford used flatheads (assuming that's a Ford)? Although Ford's first V8 was in '32, I think Chevy waited until until '55 for their first V8--an overhead. And I think the '55 hemi was mopar's first V8. I think they had only flathead sixes before that. I always remember Buick's first V8 was in '53 because that's when Guild started. I think Buick and Pontiac had only overhead straight eights before that.
The firetruck with wheelie bars is the next best thing to blues with 12 bars.
I'm stumped by whatever that is on the back of the third one. Is that a camper? And does it have two staggered carbs? He probably had four carbs originally but had to cut down on his carb intake.
