Back in 1953, Topps issued the first World On Wheels series of trading cards, eventually honoring 180 different vehicles. Collector Chuckman has scanned and posted them all on his site, and some are seriously cool.

I've excerpted a gallery of 50 of the more interesting ones below, but you'll find plenty more at the Chuckman's site. Long-forgotten makes of the 1900s- say, the Mercury Mystiques and Hyundai Excels of 100 years ago- seem to be fairly heavily represented, and there's a fair cross-section of industrial and military machinery as well.
