Steve,
If your bulb is like Tim's image, the name of the character is "Reddy Kilowatt". This is a figural neon glow lamp, one of a handful of designs that is highly desirable and which, in excellent condition, may fetch $150-$300 on eBay. Some of the others in this price range are Popeye and Mickey Mouse. There are literally dozens of styles of these bulbs (perhaps hundreds), most of which sell for less than $50. There are even some in current manufacture that retail for less than $10. I'm sure Tim and others here can give you a lot more info.
