L&M Arts gallery is serving Andy Warhol’s Campbell’s Soup in a form less familiar than the realistic red-and-white images of 1962’s Pop Art landmark.

The Manhattan gallery has assembled 12 of the 20 existing multicolored Campbell’s soup cans that Warhol painted in 1965. This is the first time they have been the sole focus of an exhibition, and the effect is remarkable.

By adding more colors to the palette, the artist transformed his original silkscreens and in the process stepped beyond his roots in the graphic arts. Greens, yellows, purples and blues fill the labels, and no one hue is identical to another in the 12 joyful paintings.

Warhol’s sharp use of color combinations gives each a painterly uniqueness where once they were only distinguished by flavor.

Two works are for sale and prices will be provided upon request. A colored Campbell’s soup can fetched $3.4 million at Phillips de Pury & Co. in 2007.

“Andy Warhol: Colored Campbell’s Soup Cans” is at 45 E. 78th St. through June 11. Information: +1-212-861-0020; http://www.lmgallery.com/.

Avedon, Gorky

Francis Bacon in black stares at visitors as they enter “Avedon: Artists” at Manhattan’s Gagosian Gallery.

The 1979 print, from an edition of 10, hangs alongside other portraits of artists, among them Duchamp, Picasso and de Kooning.

A blond dog lovingly looks up at Robert Frank, with his paw resting on the photographer’s arm. Andy Warhol shows off the scars left in his midrift by Valerie Solanas.

Also on view at Gagosian’s uptown space is a show revolving around the discovery, last year, of Arshile Gorky’s “Untitled (Pastoral),” a 1947 painting that had been hidden behind “Pastoral” -- on the same stretcher -- for more than 60 years. The exhibition focuses on the artist’s last year of life, before he committed suicide in 1948.

The challenging canvas is covered in dark brushstrokes and features an evil-looking face in the top left area with only one blue eye. In “Pastoral,” a green dog seems to be slowly stepping out of Gorky’s original yellow universe.

Not to be missed is “The Limit,” a gray abstract canvas decorated with patterns made of colors and thin lines, last shown in a retrospective at the Guggenheim Museum almost 30 years ago.

Some works are for sale, although the gallery won’t disclose prices. “Avedon: Artists” and “Arshile Gorky: 1947” are at 980 Madison Ave. through July 8 and July 1, respectively. Information: +1-212-744-2313; http://www.gagosian.com/.
