A westward view of the massive Rotunda Concourse. The entry into the equally huge Train Concourse & Waiting Room is visible in the distance. The 2 main UNION TERMINAL mosaics are also in view. On the left is "The Development of the Nation." On the right , "The Growth of Cincinnati." These and other interior works were created by German artisan Winold Reiss.

In this Rotunda view, "The Growth of Cincinnati" mosaic may be seen almost in its entirety. From right to left, it chronicled the development of the Queen City from its Fort Washington settlement (1788), through the riverboats of the 19th century, and ending with construction of the TERMINAL structure in the early 1930s.
