The Oklahoma Historical Society tells an old familiar story:

Located on the southeast corner of Grand and Harvey, the Biltmore Hotel was conceived and built during the Great Depression by prominent civic leaders, headed by Charles F. Colcord. Designed by architects Hawk and Parr, by the time it was completed in 1932, the Biltmore was thirty-three stories high and was heralded as the state's tallest building. Financial woes plagued the hotel throughout most of its life and the doors were closed in June 1973."

Of course they were. These things were cursed. They blew it up in 1977.

I wonder if KOMA radio played "easy listening." Or perhaps just a dial tone.
