Something"s glowing out in the desert night, but it isn"t New Mexico, and these creatures aren"t visitors from another planet. There is a pig with wings--who may well be fleeing the Nevada barbecue establishment he advertises--and a creature who looks something like Elmer Fudd with a lightning bolt for a body. But that"s as close as we get to alien beings, unless you count the penguin in a ten-gallon hat and cowboy boots. These colorful images of cartoon cowboys, cowgirls, women bathing in martini glasses, and martinis sans women illuminate an aspect of Americana--the neon sign--that has been largely neglected.
