“Vehicle insured by Smith & Wesson” (bumper sticker)

Smith & Wesson is a firearms manufacturer. A popular bumper sticker is “This Car/Vehicle Is Insured By Smith & Wesson”—that is, the driver carries a Smith & Wesson firearm for protection.
 
The bumper sticker slogan “This car insured by Smith and Wesson” has been cited in print since at least 1978.
 
“This vehicle protected by anti-theft sticker” is a jocular alternative bumper sticker.
