A signed sketch by Albert Einstein is to cross the block at RR Auction with a minimum bid of $5,000 on January 22.
It appears on a postcard addressed to Arthur Ruppin, a Zionist leader who was among the founders of Tel Aviv. Einstein wrote it while on a visit to Palestine in 1923.
"To my dear Mr. Ruppin, We are having unforgettable days in Palestine. With the sun shining, in cheerful company. Your wife is standing next to me and looking at what I am writing about her. She is counting the days until you come back."
Below this Mrs Ruppin writes: "Dear Arthur, A pleasant tour of the city. Included is a picture by Prof. Einstein."
RR Auction comments: "An extreme rarity, letters written by Einstein during his singular Palestinian trip are virtually unheard of; no examples have appeared at auction for the past forty years.
"And although Einstein was known to accomplish drawings, signed self-portraits are virtually inaccessible���research indicates only three other examples, none of which have been offered publicly."
Also on offer is a major archive of letters, around 1,000 pages in total, written by Einstein to hydrofoil engineer Wsevolode Grunberg from 1939 to 1948.
It also carries a minimum bid of $5,000.
