Description
Black and White 9″ x 12″ ad for their Coal Flow System. It has a picture of two men standing in a basement that is empty except for the Coal-Burning Furnace. The visitor is asking the homeowner “But how does the coal get to the furnace?” and the homeowner answers by pointing to the ground and saying that “It flows from the coal bin along here”. The headline claims that “Coal now the finest and most economical form of automatic heating” and that if you purchase this unit it “Does away with Coal Handling”. The text claims that this unit “uses inexpensive sizes of coal” and that a Coal Flow model could be purchased for as little as $10.72 per month. There are small diagrams that help explain this unit, how the closed coal bin is conveniently out of the way and how the driving mechanisms can be located at the side or the back of the furnaces.
