Designed to deter hitchhikers, this porcelain sign was attached to the door of a delivery truck as a warning. Measuring 7 inches tall by 10 inches wide, the cobalt blue letters stand out nicely on the white background. The sign reads “Warning” “The Driver Of This Vehicle Has Been Instructed Not To Allow Anyone To Ride.” “Do Not Ask Him.” The outer corners feature the original grommets, and the sign has some minor chipping around the outer edges. It is stamped “Industrial Products Co., Phila., PA.” along the bottom right edge. 21274-ETP
