SANDWICH — Heritage Museums and Gardens may be best known for its lush, colorful grounds, filled with showy Dexter rhododendrons, deep blue hydrangeas, and daylilies in every hue. Or maybefor its collection of more than 30 vintage automobiles. Or perhaps the 100-year-old working carousel. Seen all that? This season the special exhibitions gallery presents “Norman Rockwell: Beyond the Easel,” featuring more than 150 works by the famous illustrator (1894-1978). The exhibition takes two approaches to the artist’s work developed by the Norman Rockwell Museum in Stockbridge. The first brings together prints of Rockwell’s study photographs and original paintings and drawings linked to the photos, affording a frame-by-frame view of the development of some of the artist’s best-known images. The second part displays original oil paintings that explore the doctor-patient relationship, health, and healing. 67 Grove St., 508-888-3300, www. heritagemuseumsandgardens.org. Adults $15, children ages 3-12 $7, under 2 free.
