A highly collectible item among fans of the Lincoln Highway is this Texaco Road Map which shows the entirety of the transcontinental route. This map was reportedly published only once, in 1929, at a time when The Texas Company was aggressively marketing the "well-known Texaco Red Star with the green T [which] shines forth on the highways of the country from Coast to Coast." The Texaco brand did in fact become the first gasoline to be marketed in all 48 states.
Copied herewith is Section 3 of an eight map set, showing the route of the Lincoln Highway between East Liverpool, Ohio and Fort Wayne, Indiana. Note that between Mansfield and Delphos, the route of the Lincoln Highway was still marked along State Route 5, with U.S. Route 30 being marked on what were then better roads through Marion, Kenton, and Lima. Also copied is the artistic and nostalgic map cover, printed in shades of red and green, the two prominent Texaco colors.
The map images are from the collection of Lincoln Highway Association member David Cole of Santa Maria, California.
