Old, aftermarket hub caps keep finding me lately, and some of them are just hilarious. Inexpensive replacement caps were sold by companies like Western Auto and J.C. Whitney, but the logos had to be altered enough to avoid pesky trademark infringement laws. Some of them are pretty good facsimiles thereof, like this Cadillac replacement cap. It is heavy duty and looks like the Caddy emblem, but has lines instead of ducks:
This one has stars instead of ducks.
Frankly, they both look better than the modern Cadillac version that has been sanitized of its history and personality. For Chevy replacements, a dash was commonly used in place of the bowtie:
This one is for a 1954 Chevy, and it is a pretty good copy, too. You have to look hard to see that it is a dash and all one piece (the real ones have a separate center insert).
The really entertaining versions are the ones with altered spelling. I have seen dog dishes that say “Dodoe” instead of Dodge, for instance. The Chrysler replacement cap pictured below says something like “Clrrfrlir, although the “i” is mysteriously undotted.
This is one of the famous “Bool” caps made for a Model A Ford:
I have heard that they also made a “Fool” version. I’m not sure who would want to drive around with those on their car (but I know of a few people who should).
