Curtis Oil Company, Marathon gas station. Located at the crossroads of Illinois Routes 54 and 121, Mt. Pulaski, Illinois. View looks north, as both roads run at an angle here, with Route 54 running NE-SW, and Route 121 running NW-SE. The sign just pass the gas station reads that it’s 12 miles to Kenney, and 25 to Clinton, along Illinois 54. Since this picture, Route 121 has been rerouted to the south, and crosses under Ill. 54.
