The mudflap girl is an iconic silhouette of a woman with an hourglass body shape, sitting, leaning back on her hands, with her hair being blown in the wind. The icon is typically found on mudflaps, clothing, and other items associated with trucking in the United States. The image is sometimes also known as trucker girl, trucker lady or seated lady. This famous design was created in the 1970s by Bill Zinda of Wiz Enterprises in Long Beach, California, to promote his line of truck and auto accessories. It is variously claimed to be modeled on Leta Laroe, a famous exotic dancer at the time, or on Rachel Ann Allen, a friend’s wife, and mother of Ed Allen, the trademark’s owner.
As a parody, Wyoming Libraries use a mudflap girl holding a book, in an effort to attract readers. In another parody the feminist blog Feministing uses a version depicting the mudflap girl holding up her middle finger as an ironic logo. Optimus Prime has been portrayed as having a mudflap with the silhouette of Elita One (leader of the female autobots). At McMurdo Station, Antarctica, the mudflap girl is depicted on a utility vehicle, but wearing more appropriate attire for Antarctic environment.
