Up for sale is a rare, original. Real Photo Postcard (RPPC). This stunning image shows the tractor parked in front of an International Harvester Co. Building, with the company name clearly visible on the door in the background. The image is sharp with excellent contrast for its age. The “Mogul 10-20 Tractor” caption is clear at the bottom. There is light surface wear and minor corner rounding consistent with age. And has not been stamped. There is some vintage pencil handwriting (notably “Lulu Nell Wiley”) and “KRUXO” branding in the stamp box area, which dates the photo paper to the early 1910s. Please see the high-resolution scans for a closer look at the edges and surface texture. The Mogul 10-20 was produced by the International Harvester Tractor Works in Chicago. It was a pioneering kerosene-burning tractor. This postcard likely served as a promotional piece or a proud souvenir for a farmer or employee.
