You know, I've never given much thought to the "mudflap girl". I grew up seeing her on nearly every 18 wheeler in the country, and since have seen her on hats and shirts and stickers and so on and so on. With a quick google search I discovered she's the product of Bill Zinda, who came up with her to promote his trucking products. And she's been going strong ever since. And now we can enjoy her curvaceous silhouette in bricks thanks to builder bricksnoir.
