TLS signed “A. Einstein,” one page, 8 x 9, blind-stamped personal letterhead, February 4, 1941. Letter to Charles Potter. In full: “I was really delighted with the content of your kind letter of January 13th and I congratulate you for the courage and resolution to follow a difficult path outside the traditional religious organizations. I have not the time and not the ability to address your meetings, but I shall be glad to join your advisory board.” Double-matted and framed with two portraits of Einstein and a quote about mathematics to an overall size of 28.75 x 16. In fine condition, with intersecting folds, paperclip impression to upper left corner, and a faint block of uniform overall toning, not affecting the crisp signature. In 1929, Potter founded the First Humanist Society of New York, whose advisory board would include Einstein, Julian Huxley, John Dewey, and Thomas Mann. Oversized. Pre-certified John Reznikoff/PSA/DNA and RR Auction COA.
