Here are three postcards from northwest Ohio showing an early Lima-Indiana oil field oil gusher. The two color versions (one attributed to Bowling Green and the other to nearby Lima) show a black horse that postcard “retouchers” added to the scene. The crudely added horses are not quite the same on the two postcards…note the legs. The postcards were also cropped differently and the coloring is different. The sepia-toned Lima postcard (without the horse) and the colored, Bowling Green version were both postmarked in 1908.
