Auction introduction: This year's Master Paintings & Works of Art Part I sale—the first to be held at the iconic Breuer building on Madison Avenue—presents a wonderful selection spanning the full breath of the category, from early Italian Renaissance gold grounds to eighteenth-century Venetian vedute and English portraits. The sale is led by Antonello da Messina's exceptional double-sided panel depicting the Ecce Homo, dating to circa 1460-1465, the artist's only treatment of that subject presently known to remain in private hands. Other highlights include Jean-Honoré Fragonard's expressive head study of a bearded man; a magnificent millefleur unicorn tapestry of circa 1500 from the celebrated collection of Cindy and Jay Pritzker; and a hauntingly intimate Roman Egyptian encaustic on wood Mummy Portrait of a Man, acquired by John Franklin Goucher in 1895. The auction also features paintings from the esteemed collections of Dr. Heinrich Bischoff, Anne W. Lowenthal, Ambassador J. William Middendorf II, Stanley A. Moss, and others.
