I added this Lockheed VC-140B “Jet Star” 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 C-140 is the military version of the Lockheed Model 1329 light jet transport. The USAF bought 16, six of which were flown as VC-140Bs on special government and White House airlift missions. The VC-140B on display at the National Museum of the U.S. Air Force carried Presidents Nixon, Carter, Reagan, although it was the not the primary presidential aircraft.
