1.75" with Bastian backpaper used only 1906-1907. Beautiful scene from elevated perspective shows large factory buildings in red with smoke coming from their stacks along with a huge building which is apparently a grain elevator which has steam locomotive and freight cars parked on the siding next to it. Numerous tiny depictions of horses, carriages and people plus a flag flying from a rooftop and in the distance on the "Office" building. The motto above is "Use 'Hunter's Cream.'" Heavy oxidation on half of reverse collect with dark stain on lower curl but only a trace shows on front bottom edge. Still displays beautifully. Our last with small edge marks exceeded $300. Gorgeous and rare.
