98.United Air Lines - All Other PostcardsThis folder includes the postcards related to United Air Lines that are not part of the company's first issued Black & White series. That series is in an album by itself. United Air Lines was formed in 1931 combining Varney Air Lines, Pacific Air Transport, National Air Transport, and Boeing Air Transport under the parent company United Aircraft and Transport Corporation. After the 1934 Air Mail Act United Air Lines became an independent airline headquartered in Chicago. This album starts with the airlines which initially formed United Air Lines and all other postcards related to United Air Lines besides the significant 1932-1940 Black & White series. There are both company issued cards and postcards from others. With the company issued Chrome postcard series there were so many cards related to Hawaii I separated them out. United promoted the Hawaii trips via Stratocruiser and they make a nice group of cards. As with the rest of my collection the cut off date, with a few exceptions, will be postcards made 1959 or earlier. The exceptions are usually airport postcards that run into the 1960's.
