Carter Burden Gallery (548 West 28th Street) is unveiling Contemporary Works by The New York Botanical Garden’s Botanical Art and Illustration Certificate Program. This month a selection of 17 works by 14 NYBG instructors and graduates is on view at CBG, which champions the creativity of older, lesser-known artists, especially New York City residents older than 60. The show’s concept was originally suggested to both partners by Pata Llano of the art materials supplier Dick Blick, Inc.
