King papers on auction

The personal papers of Martin Luther King, including his I have a dream speech, will be auctioned as one lot in New York this month following the failure of efforts to negotiate a private sale.

Sotheby8217;s auction house, which described the collection as the 8216;8216;most important American archive of the 20th century in private hands8217;8217;, said on Thursday that the public sale would be held on June 30.

The lot, valued as high as 30 million, comprises King8217;s personal library as well as manuscripts and papers that passed to his family following his assassination in 1968.
