I added this Boeing B-1B “Lancer” 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 B-1B is an advanced bomber that features a swing wing that allows it to perform well in high subsonic and supersonic flight. It also employs forward-looking and terrain-following radar that enables it to fly at very low attitudes in all kinds of weather. Its extremely accurate Global Positioning System/Inertial Navigation System, Doppler radar, and radar altimeter help aircrews navigate around the world without ground-based navigation aids.
