More than 200 items are up for sale at the Doyle New York auction house. The items range from a sequined evening coat estimated to sell for as little as $100 to an abstract painting by African American muralist and artist Charles Alston expected to rake in up to $50,000.
Also, a mink coat by Horne's favorite designer, Giorgio di Sant' Angelo, is estimated to sell for $300 to $500. A Chanel five-strand choker of gold-tone metal links and faux perals had a $1,000-$1,200 pre-sale estimate.
Horne, who was also a dancer and civil rights activist, died last May at the age of 92.
