This ad was published in the February 7, 1942, issue of the Saturday Evening Post, pg. 31.

UPDATE: I’ve updated these images with corrections and four additional ads. You can a similar listing of Collier ads in black and white.  I’ve added two ads that only appeared in the CIO-News, one that only appeared in Colliers, and one Sat Evening Post ad that I’d missed.

Original Post (03/01/2019): I tried to find a listing of all the Willys-Overland ads and their issue dates that were published in the Saturday Evening Post during and after WWII. Unable to find any good resource, I spent the last three days surfing through 250 issues of the magazine using the Saturday Evening Post non-profit site, which costs $15 a year to use. Then I organized them in a way that I hoped would make it easier for me to study them. Hopefully, it’s handy for you all, too. For expediency and bandwidth size, I used low-resolution images to create the files below. Eventually, I’ll go back and replace them with hi res images so that everything is clearer when viewed more closely.

The ads started in May of 1942 (at least that’s the earliest I found) and were published on average once a month. All ads published up to November of 1945 were placed on the inside of the back cover.

On November 10, 1945, Willys-Overland formally introduced the CJ-2A to Saturday Evening Post readers with a more centralized, two-page ad. After that, one or two-page ads for the CJ-2A appeared until August of 1946, when the first wagon ad appeared in the magazine.
