These Zippos feature Reddy Kilowatt.  He's a stick figure made of lightning bolts, with a light bulb for a nose and wall outlets for ears. His hands and feet are insulated, and instead of hair, he has a smaller pair of twin lightning bolts. He first appeared on power company advertising in 1926 and was used as a mascot by hundreds of electrical utility companies.  He first appeared on the Zippo in the early 1950's.
