"The Art Show," under way through Sunday in New York, is the first group exhibition organized by the Art Dealers Association of America, and the first show of its kind for the city.

Fifty-seven art dealers are showing paintings, sculptures, prints, drawings, photographs and objets d'art, all for sale, in Manhattan's Seventh Regiment Armory. Exhibits span six centuries of art history, from a 1490 Mantegna etching to enormous canvases by Roy Lichtenstein and James Rosenquist. Works also include the Rembrandt etching, "Self Portrait Leaning on a Stone Sill," and "Tete de Femme au Collier" by Matisse.
