Martin Luther King Jr. was planning a trip to the Soviet Union after surviving an assassination attempt, and his letter explaining his reasons for the visit is up for grabs.
The famed civil rights leader was only 2 months removed from being stabbed at a book signing in Harlem when he wrote to the National Council of Churches, explaining his motivations behind a visit to the USSR.
One really eye-opening part of the letter is the price ... MLK estimated the trip would cost a whopping $35 per day for his hotels, trains, planes, interpreters, cars and chauffeurs. Yeah, different time -- today that would be about $370 per day.
The rare piece of MLK history is going up for sale through Moments In Time for $54,000 ... after being stored for years by a private collector.
