In 1987 the company created the first window-mount auto sign for the food service and delivery industry. At that time, the only options were rooftop signs mounted with gutter-hook straps and suction cups. Amount the problems, late model vehicles were being manufactured without rain gutters. Tracy owned a gourmet sandwich delivery business catering to the downtown business community. He identified with industry objections and developed the window-mount sign as a result of his delivery drivers concern of vehicle roof damage and the loss of several large, custom die-cut magnetic signs. The window-mount design set an industry standard for optional delivery sign installation.

The company's first window-mount auto sign was a lighted, moving windsock called the AutoSox which caught the attention of pizza delivery companies across the country. With a better way to install delivery signs at a breakthrough price, AutoSox USA manufactures a complete new line of retro-shape and custom shape delivery signs. The company was then issued patents for certain window-mount sign improvements.
