George Deem (Allan Stone Gallery; to Nov. 9) is superbly able to lift from his subjects their face values and carry out his own purposes with a beautiful disregard for the historical demands. Recent work concerns master paintings, not as pop art, but, traditionally, as subjects. The Hals lady with tankard and owl is repeated six times and has six distinct and inventive statements to make about color, light, jokes, paintings. A Painting for a Library, a warm grisaille synthesis of every nineteenth-century Greco-Roman Information Desk portrait, looks at the toga-set in coffee-break attitudes and makes mock of style and subject directly yet marvelously. Deem is not content with parody, but builds a taut luminous painting to complete his image of himself. His Degas', Corots, English portraitists are born with their own beginnings as Deem paints a new work every time with sensitive, serious dynamics. (Prices: $150-$650.)
