1917 Heider Model C 12-20 Traction Engine & Briscoe Automobile Magazine Ad

This original 1917 magazine ad is a rare find as it has two scarce products advertised, both deserving a place of honor in someone's advertising collection.    The page has been partially trimmed but both ads are intact, unfortunately they are on the front and back of the same page.  Page 35 features a Heider Model C12-20 Traction Engine Tractor made and sold by Rock Island Plow Company, fantastically illustrated.  Page 36 features the rare Briscoe 5 or possibly 7 passenger touring car, Briscoe made cars out of Jackson, Michigan between the years of 1914 and 1921, so to find an ad is truly special.
