In the upper portion of this photograph you see an orange trade card from Munn & Co, publishers of Scientific American, advertising their American and European Patent Agency. To the right of that there is the fancy leather sleeve for a patent that the agency obtained for Louis A. Lyon of Shortey's Depot, Alabama, for a railroad car heater with an automatic fire extinguisher. The patent that came in the sleeve is also displayed. (The patent had been folded in the sleeve for so many years that it required heavy blocks to hold it flat for the photograph.)
