This is a vintage advertising print featuring “Mr. Harness-Maker” a horse harness oil dye by the Leo Hofmeister Company, based in Milwaukee, Wisconsin. The ad showcases a black and white color scheme with a theme centered around harness oil. This original piece of merchandise and memorabilia serves as a unique collectible for those interested in advertising and vintage memorabilia. Backside photo portrays the inside of a harness shop and how the harness oil basket works. Has been folded to put into an envelope, so there are two creases with light staining on photo side. Looks like 1900 era.
