A vintage postcard view of the Train Concourse and Waiting Room, which was demolished in 1974. The murals along the sides were fortunately removed and reinstalled at a new terminal at the Greater Cincinnati International Airport (now the Cincinnati / Kentucky International Airport). Unfortunately, the large US map mosaic was destroyed along with the Concourse structure.
