Adjectives such as "featherweight'' and ''paper-thin'' neatly suit D. Berman  Gallery's ''Works on Paper'' show. Paper, after all, is an ephemeral material, especially unframed, and a lightness suffuses the art in this immaculate gallery. 

Nevertheless, Randy Twaddle's charcoal-bruised banners convey a roughness through bold lines, dark masses and ghostly shadowing. Beverly Penn's copper sheets mimic spiral-notebook pages, her cloudy markings reminiscent of ancient artifacts. Lauren Levy's oils brightened the gallery with sparkling  images of puffy dresses and other tokens of a girl's life.

Ed Ruscha's ''Sunliners'' series appeared, at first, oversimplified. Yet the smooth aquatint lines representing water vessels float elegantly over grainy and etched surfaces, evoking a thoughtful reticence. A mystical bent informs Lucas Johnson's pen and ink drawings, with cross-hatched heads and hands doubling for leaves, birds and other patterns. Margo Sawyer is represented by two spatial exercises overlaid with wax, copper foil, lead, graphite and ink,  as well as gold and silver leaf. 

Dee Wolff's lively gouaches soak color into fabriclike Pondicherry paper, then inscribe sailboats, trees and other images, repeated and garlanded in  jewel colors. The ''One of These Is Not Like the Other'' series from Marjorie Moore reposition a monkey poppet over sand-colored paper tagged with enigmatic symbols, increasing their sense of mystery.
