\"Pan am\'s Pacific Pioneers traces the the development of air mail and passenger flights across the Pacific from the building of the island bases at Wake and Midway in 1935 to the last Pacific Clipper flight in April 1946 when Pan Am\'s flying boat era came to and end. By featuring the first flight souvenir covers as well as Pan Am\'s pictures, brochures, and time tables the hard work, frustration, tragedy and the ultimate success of Pan Am\'s trail blazing efforts is fully documented. Those who collect first flight covers will enjoy seeing the covers in color and even those who don\'t collect them will still enjoy the wonderful stories that they tell.\" Very good condition.
