One of my favourite stamp sets is the American Airmail stamps issued in the summer of 1947. The 3 value set features prominent aircraft and landmarks of the time. The stamps were printed by rotary press and are perforated 11 x 10½.
The 10¢ value features the Martin 2-0-2 and the Pan American Union Building in Washington DC. The Martin 2-0-2 first flew in November of 1946 and was built as an intended replacement for the venerable DC-3. With a production run of only 47 aircraft, these aircraft were in operation until the mid-1970s. The major operators of the 2-0-2 were Northwest Orient Airlines, LAN Chile and Trans World Airlines.
