The Old Car Manual Project has a new website dedicated to original ads for old cars, called oldcaradvertising.com It’s a comprehensive collection of high resolution scans of over 12,000 ads, mostly from magazines, and covers the period 1903-1989.

I believe it’s the largest collection of classic car advertising on the web, and of course, it’s free.

Of related interest is the collection of brochures, which contains over 40,000 images, at oldcarbrochures.com
