Here's another piece of presidential history that is purely for educational purposes. A recent letter from one of JFK's rumored mistresses has sold at auction for $4,500 and recounts a close relationship with the President and their arranged visits at "Paul's house in Georgetown". That house is on Prospect Street, says a local historian, and is pictured above. We would show you a picture of the letter that sold at auction, but since it has a hand-drawn rendering of a topless woman we thought it better to provide the link instead. Happy President's Day.
