Published in 1988, 'Lockheed U-2R/TR-1' is number 28 in the Aerofax Minigraph series of aviation booklets. This booklet focuses on the final variants of the Lockheed U-2 reconnaissance aircraft, and was published shortly before the end of manufacturing of the type. The text is a little dry, but extremely detailed and is supported by well over 200 excellent photos and many other illustrations. Very informative.
