The collection was housed at NAME_5's six-storey New York townhouse. The 51-year-old designer was shot outside his Florida home in 1997 by suspected serial killer NAME_6, who later killed himself. The auction, at Sotheby's, will feature 45 contemporary, impressionist and 19th Century paintings. One of the highlights of the sale is NAME_2's Blue Nude which has been given an estimate of £1.8m ($3.4m).NAME_7, Sotheby's worldwide head of contemporary art, said: 'This collection reflects Mr NAME_5's wide-ranging taste and impeccable eye, and many of the works were commissioned directly from the artists. 'Outstanding later examples from champions of the Pop movement, such as NAME_2, are juxtaposed with masterpieces from the most visible artists of the 1980's, including NAME_8 and the collaborative genius of NAME_9 and NAME_10, as well as NAME_11.' Much of the collection will be offered for sale at three auctions in New York in June, with smaller contemporary paintings going under the hammer in London on 22 and 23 June. A sale of NAME_5's furniture and artworks sold in 2001fetched £5.5m ($10.3m).
