“Slipping Girl” History

Our “Slipping Girl” mascot has been a long time favorite. She’s done in a classic pin-up style artwork that was popular with mechanics and WWII era military personnel. The original sketches, dating back to the early 50’s, included ice skates on her feet and an oil pan gasket in her left hand. The vintage 1950’s grand prix racer symbolizes our dedication to performance.
