Beginning Aug. 23, The Gallery at David Ryan Salon (429 West 46th Street) will exhibit Hull's artworks, which range from watercolor landscapes to graphite portraits to multi-layer wax crayon rubbings. The images are all theatre related, some taken from the lavish Broadway revival of 42nd Street, some from the poor cardboard sets of community theatre productions. Others sources include the Jerry Lewis road show of Damn Yankees, in which Hull played Lola, to the PBS broadcast of Crazy for You . The show will be open to the public through Nov. 3. The opening night reception is at 6 PM Aug. 23.
