OilPull Motor Oil Sign

Made in U.S.A. 1920 - 1931. Single-sided tin (SST). Embossed. Advertising triple tested, dewaxed, tractor oil. Paraffin wax naturally occurs in crude oil and would crystallize in cold temperatures, causing oil to thicken and engines to seize. In the 1920s, the chemical process of "dewaxing" motor lubricants was a massive breakthrough. The company was acquired by Allis-Chalmers in 1931. Marked, "AMERICAN ART WORKS INC." lower right. Authenticated by The Authentication Company (TAC #402896.). All items are guaranteed authentic by Miller & Miller Auctions. All purchases are eligible for free delivery to the Winter 2026 Dixie Gas Show on December 4th. From the Barry Yorgason Collection.
