WILTON, CONN.- A vintage black and white pin-up photograph of Marilyn Monroe taken circa 1947 and signed by the budding starlet, a two-page typed letter signed in German by Albert Einstein in 1935 containing mathematical equations and edits in his hand, and a handsome Civil War-dated military commission signed by Abraham Lincoln are just a few of the expected top lots in University Archives’ upcoming online-only auction planned for Wednesday, April 10th.

The Rare Autographs, Manuscripts, Books & Memorabilia auction will start at 10:30 am Eastern time.

“The carefully curated lots in our April auction offer collectors a great buying opportunity,” said John Reznikoff, president and owner of University Archives. “The catalog is especially strong in U.S. Presidents, Science, the Arts (Literature, Art & Music), Entertainment, Civil Rights, Early America and Sports. It’s a rarer chance to acquire outstanding autographed material, historical documents, rare books, photographs, relics and memorabilia from many collecting categories.”

Lot 315 is the two-page typed letter signed in German by Albert Einstein on Sept. 14, 1935, with mathematical equations and edits in his hand.
