MoToR was an American car magazine published monthly. Every January a show issue was printed which contained all the specifications of new cars on the market. I have the 1921 and 1923 issues in my small library. The 1923 issue is very thick; it has over 400 pages. I think the last MoToR show issue was published in late-1930's. I'm not sure when the first one appeared.
+ Beautiful cover art
