The purpose of this brilliant marketing campaign by the Wyoming Libraries is to promote their searchable online Chilton automotive database (a useful thing of you happen to be the handy type who knows the difference between a distributor cap and a baseball cap).
According to their site:
Mudflap girl stickers meant to be put on vehicles, were sent to auto repair stores across the state advertising the Chilton database.
I tip my hat to the folks who marketed this in Wyoming. Very clever.
