A consoling letter sent from President Lyndon B Johnson to the widow of Martin Luther King is to cross the block at Quinn's Auction Galleries in Virginia.
It's valued at $120,000-180,000 ahead of the March 19 sale.
The letter dates to April 5, 1968 - the day after King was murdered.
It reads, in part: "Since early morning, I have devoted all my hours and energy to honoring your good husband in the manner he would most approve. I have sought --by word, deed, and official act - to unite this sorrowing and troubled nation against further and wider violence�Ǫ
"We found more than grief to share. I wanted you to know tonight of the determination that binds us: We will overcome this calamity and continue the work of justice and love that is Martin Luther King's legacy and trust to us.
"I am also determined that the assassin will be found and punished. The full powers of local and Federal authority are marshaled now to assure it�Ǫ
"I believe, with all my heart, that the American majority will also be guided by them, in goodwill and great hope. All of us ask God to comfort you now and restore your compassionate influence to us. Sincerely, Lyndon B. Johnson."
