Notes:
This pictorial map of the U.S. shows major products in each state dependent on shipping by commercial trucking. Around the border are images of 32 vehicles, from the fire truck to the ice cream truck. It was produced in 1958, two years after authorization of the Interstate Highway System - which facilitated travel by larger trucks at higher speed - and at a time when federal weight limitations on trucks were under discussion. It is possible that this map was part of a lobbying campaign by its publisher, the Automobile Manufacturer’s Association. (For example, a note at the bottom right of the map states that "Any portion of this map may be reproduced editorially in newspapers and magazines" with attribution.)
