It reads in part: “Why don’t you leave suburbia for once — come and see me — either here –or at the Cape next week or in Boston the 19th.” It goes on to say that such a meeting is “unwise” and “irrational.”

The letter is believed to be one of the last notes the former president ever wrote before he was assassinated in Dallas, Texas nearly a month later.

The online sale is being held by Boston-based RR Auction starting June 16.
