"Western Cattle in Storm" $2 orange brown – "Mississippi River Bridge" (the Eads Bridge) The designs were adapted from various photographs, drawings, and paintings; both the 8¢ and 50¢ values reproduced drawings by Frederic Remington. While all have been praised for their quality, the $1 value, commonly called the "Black Bull", stands out from the rest. Ironically, it does not reproduce a Western American scene, but was taken from a painting of cattle in the Scottish Highlands by John A. MacWhirter (see also Western Cattle in Storm). The vignettes of the issue were executed by three engravers: Marcus Baldwin (2¢, 5¢, 10¢, $1), George Smillie (1¢, 4¢, 50¢, $2) and Robert Ponickau (8¢). Baldwin also engraved all the frames except that of the 2¢ stamp, which was the work of Douglas Ronaldson—- who in addition engraved all of the numerals and lettering of the Trans-Mississippi series. The 2¢ stamp violates the convention of the time that no living person could be depicted on a U.S. Postal issue. In the photograph of North Dakota harvesting that served as the basis for the engraved vignette, the three figures in the foreground have been identified as the farm worker Ed Nybakken, the field boss Elihu Barber and the foreman Sam White. During 1998, to commemorate the 100th anniversary of the issue, the United States Postal Service issued a miniature sheet of the nine, each printed in two colors, and a sheet of nine of the "Black Bull". In most of the images, the original color scheme was preserved, but for the "Black Bull" the hue of the frame was changed from violet-brown to bright red. The designs are reproductions; each has a small "1998" in the lower left corner. In a revival of the original designs, the pictures in the 2¢ and $2 stamps were swapped, and "Farming" was changed back to "Harvesting."
