A comment on an earlier thread that I posted inspired me to do some internet digging for advertising cars. What I found was quite interesting. Some forms, such as bottles are easily adapted to automotive form, others need a little persuading.
Here's an English fruit vendors truck with apple shaped cab. Ford model AA (truck) chassis.
Another English Ford, this one is a Model T from Sillito's, a bakery that had a high opinion of itself. The rear must represent a loaf of bread; the front a muffin. Notice the very retro - for the time - horse drawn type coach doorhandle, which was favored by Bugatti.
PepOMint life savers, a dainty confection. This adcar is anything but dainty, as a matter of fact, it looks down right dangerous to both the driver and oncoming cars, horses, small children, etc.
Space age! It would have been hard to miss this late 1950s French device.
More space age - but this is waaaaaay before it's time. This Benson, Minnesota Monitor-News rocket powered Zeppelin must date from the 1920s . Actually, I doubt if it's rocket powered; but I really like the idea.
More space age! The Mars Express from Golden Glow Beer, late 1930s. It this is still out there, I rate it as the ultimate barn find. Golden glow - yes, I know that feeling.
Worthington's Ale bottle on a Daimler chassis. Worthington's knew quality when they saw it.
Beer from the wild wild West - Billings, Montana. No mistaking what this brass era car is advertising.
Stover Candies had a thing about bungalows. This is the only advertising motorcycle I've found.
Freixenet champagne from the 1929 Barcelona Worlds Fair. What chassis - Hispano Suiza?
Peters Bros. shoemobile from San Francisco. Presumably a Chevy. Yes, I know, San Francisco has always been a little weird.
