Scarce circa mid-1940s hand-drawn technical diagram by Alan Shepard on an off-white 12 x 9 sheet, signed in the upper right corner in pencil, "A. B. Shepard, [SECT] 11-2, [DESK] 623." Dating to his time in the Navy while attending a summer term course at Annapolis in 1945, Shepard drafts two sketches of a cylindrical part. In fine condition.
