Autograph Letter Signed to C. C. Maxwell. No place, Sept. 26, 1857
In this wonderful letter Faraday discusses the famous experiment in which Galileo is said to have dropped spheres of different masses to show that their time of descent was independent of their masses. Though said by some to have been a thought experiment, this was one of the most famous demonstrations in the history of science. The experiment disproved Aristotle’s theory of gravity and helped usher in the era of modern science.
(APOLLO 11.) Neil Armstrong, Buzz Aldrin, and Michael Collins
Official NASA photograph of the Apollo 11 crew (1969), signed by Neil Armstrong, Michael Collins, and Buzz Aldrin, Jr. NASA, May, 1969
Signed and inscribed by the crew of Apollo 11, the first manned mission to land on the moon: Neil Armstrong (commander), Buzz Aldrin (lunar module pilot), and Michael Collins (command module pilot), with an added inscription by Armstrong.

The early photographic prints with the red numbers, such as the present example, are much more desirable than the more commonly available lithographic prints of the same poses.
(WASHINGTON, BUSHROD.) [Ballow, Henry.]
A Treatise of Equity … with the addition of marginal references and notes by John Fonblanque. Volume the Second. Dublin: Byrne, Moore, Jones, and Watts, 1795
Bushrod Washington’s copy, with his signature on the title-page. George Washington’s favorite nephew, Bushrod (1762-1829) was executor of his uncle’s estate and inherited Mount Vernon. He inherited Washington’s library and papers, and this volume was surely shelved side-by-side with those books at Mount Vernon. Bushrod Washington gave John Marshall access to Washington’s papers when the chief justice was writing his Life of Washington.
