Coal was and still is, literally, the driving force in America. Practically nothing ran without it back when these cards were produced. Coal is still the largest energy source in the country with 50% of the power produced is with coal. To illustrate this, in 1915, there were 140 coal dealers. Check your phone book and see how many you can find. Although coal is still extremely important in today's society I only found one. Mergers have formed mega Corporations.

All four cards above were sent out by The Middle West Coal Co., Inc. Their offices were in the 1st National Bank Building. The same Building where the Marmet-Halm Coal Co. were located. Not to mention The Diamond Coal & Coke Co., The Chesapeake & Ohio Coal & Coke Co., Belmont Coal, Raleigh Coal & Coke Co., Raymond City Coal & Coke co., The E. L. Sternberger Coal Co., The Waldensia Coal & Coke Co., The Winifrede Coal Co. I would think that this building was probably kept pretty warm during the winter months.
