Official NASA manual entitled "Results of the First United States Manned Orbital Space Flight" dated February 20, 1962. Prepared and published by the Manned Spacecraft Center (now the Johnson Space Center in Houston, TX).  This book documents the prelaunch activities, spacecraft description, flight operations, flight data, and postflight analyses for John Glenn's historic flight in the Friendship 7 capsule.

In fine condition except for slight cover fading from years sitting on my FIL's desk at the Johnson Space Center before he retired.  The final mission that paved the way for Apollo 11's moon landing in July of 1969.
