Unknown (cn Unknown) Don't adjust your set- the yellow color is from the lights on the airport, not the age of the card. A great night postcard of the west concourse at CLE, taken sometime between 1956 and 1961. Two UA DC-6's on the right, a Capital Viscount, Allegheny DC-3 and unidentified DC-3 on the left. Many thanks to Bob Garrard who gave me this card for my collection.
