A search brought this up:
Saturday Evening Post October 1908.
Thanks Herb, a good article featuring one of the first Model T ads. The only problem, the writer says "Ford Motor Co. had been only a modest competitor, producing a small number of Henry Ford's Model R and S vehicles."
FMC was already the largest producer of motor cars in the world. I guess the writer felt the need to add a little drama to an already great story.
And this is what that issue's cover looks like. Snagged one off eBay a long while back, this ad is the T's guy's holy grail
It seem's simple enough,he forgot the Model N!! Bud in Wheeler,Mi.
