A letter handwritten in German and signed by Albert Einstein from 1937, a two-page letter written and signed by Davy Crockett in 1834 while he was a U.S. Congressman from Tennessee, and a two-page letter written and signed by Lee Harvey Oswald to his brother from 1961 are just a few of the expected top performers in University Archives’ online-only Rare Autographs, Manuscripts, Books & Americana auction planned for Wednesday, August 7th.
