Blain Di Donna, a collaboration between former Haunch of Venison partner Harry Blain and onetime Sotheby’s Impressionist and modern specialist Emmanuel Di Donna, launches October 27 in the Carlyle hotel on Madison Avenue. The gallery will focus on secondary-market sales of Impressionist, modern and contemporary art, mounting two shows a year. The first will be a non-selling survey of René Magritte comprising 25 works, most making their New York debut and all on loan from collectors in the U.S. and Europe. “It was time to have something in New York of this scale and quality,” says Di Donna. Converting the 2,800 square foot space took much of this year, says Di Donna, but in the meantime the gallery has been busy with private sales.
