Our selection of original art ranges from comic art to a Norman Rockwell signed artist’s proof. Sports fans can find incredible signed photos and other memorabilia from 20th-century baseball and boxing legends.”

He continued, “As always, collectors of Declaration Signers, presidential, Revolutionary War, Civil War, and Americana will not be disappointed with our vast and diverse selection. Of special note are a 1776 letter by John Hancock, a great George Washington, a superb Thomas Paine letter, and even a Paul Revere signed item. There are several Jeffersons and many Lincolns, too.”

The Einstein letter – typed in English on Nov. 2, 1953, signed and addressed to George Aristotle Solounias in Athens, Greece, references “the validity of Newton’s theory” using a “clock-time” illustration.
