For our final "coat of arms" found in Omaha, Nebraska, we go to the arms-like logo of the Union Pacific Railroad Company, as mounted onto a marble wall outside the Union Pacific Center there.
The logo of the UPRR is basically a shield of the arms of the United States (well, they do reverse the tinctures of the paly field; in the U.S. arms they are paly of thirteen argent and gules, while on the UP logo they are paly of thirteen gules and argent), with the addition of the words "UNION PACIFIC" one above the other in white letters on the blue chief. Here’s a color version, photographed from the side of a UPRR boxcar.
The bottom line? It’s not "real" heraldry, but it comes close.
