Abstract: A vehicle window-mounted advertising sign for secure attachment of the advertising sign solely to the window and not requiring interface or support from the vehicle window frame. An upper window attachment includes an inner window surface mount arm which extends over the vehicle window and terminates in an inner window surface interface, combined with an outer window surface arm terminating in an outer surface interface, which when mounted on the vehicle window, impart both an inward and an outward force on the respective window surfaces, thereby securing the advertising sign to the window. Further in combination therewith is an angular adjustment feature which allows the angle of the advertising sign relative to the vehicle to be easily adjusted in an articulating manner to maintain optimum visibility and angle of the advertising sign.
