Willys-Overland filed to trademark the "Jeep" name in 1943. From 1945 onwards, Willys marketed its four-wheel drive vehicle to the public with its CJ ("Civilian Jeep") versions, making these the world's first mass-produced 4WD civilian cars. Even before actual civilian purpose jeeps had been created, the 3 Jan 1944 issue of Life magazine featured a story titled: 'U.S. Civilians Buy Their First Jeeps'. A mayor from Kansas had bought a Ford GP in Chicago in 1943, and it performed invaluable work on his 2,000 acre farm.
