I added this Boeing P-26A postcard to my collection. It was a purchase. There are facts about the aircraft on the back. The following description is also on the back:

The P-26A was the first all-metal monoplane fighter produced in quantity for the U.S. Army Air Corps. It was affectionately called the “Peashooter” by its pilots. It was the last Army Air Corps aircraft accepted with an open cockpit, a fixed undercarriage, and an externally braced wing. Significantly faster in level flight than previous fighters, the P-26A’s relatively high landing speed caused the introduction of landing flaps to reduce this speed. This P-26A reproduction is displayed at the National Museum of the U.S. Air Force and is painted to represent the commander’s aircraft of the 19th Pursuit Squadron at Wheeler Field, Hawaii in 1938.
