This CBS-Columbia ad is courtesy of Steve Dichter. It's my scan of a Xerox copy of the ad, which appeared in the "New York Times" on Monday June 25, 1951. Its text appears below in a separately scanned image.
In the lower left-hand corner of the ad, the address of CBS-Columbia was given as:
CBS-Columbia, Inc.
(formerly AIR KING PRODUCTS CO., INC.)
170-53rd STREET, BROOKLYN 32, N.Y.
