Here is the image of a probable Louis Smith forgery of the UX14 Jefferson Postal Issue of 1898.
The reverse of the card has a clay coating as is normal for most of the rare copies of this card discovered. The coating covers a faux pre-printed notice from a firm identified as "Evans & Williams" located at 944 15th Street in Chicago. The printing over the coating for the Central School Supply House was probably a legitimate enterprise.
The APS book by Petschel (See Bibliography) gives a great account of the Louis Smith story, and is highly recommended reading.
This printing on top of the clay coating identifies the year 1900, indicating that this forgery may have been in possession of and gone unused by this customer for a couple years before the apprehension of Smith by authorities. It is thought that Smith had been "in business" earlier than this, since UX12 forgeries are also known to exist.
The card exhibits the "secret mark" known for identifying these forgeries - The second "T"
in "States" missing the bottom serifs.
