Scarce original presidential pencil doodles made by Herbert Hoover on an off-white 6 x 9.5 card, headed "The President's Engagements," August 7, 1929. The page outlines Hoover's busy schedule for Wednesday morning, which notably began with a meeting with "Col. Lindbergh." Hoover marks each meeting with a large "X," adds an item, "3 p.m. Sen. King," and draws a large three-dimensional box around the name "Robinson" at the bottom of the page. In fine condition. Originally sold by pioneering autograph dealer Forest H. Sweet and accompanied by his original folder. Hoover was known for his doodles, which often reflected his engineering background—as seen in this wonderfully engineered 3D box.
