It’s called “Illustrators of Light.”

One of the current exhibitions at the Norman Rockwell Museum in Stockbridge, it’s a collection of advertisements created by Rockwell, and several of his notable peers in the world of 1920s illustration, for Edison Mazda Lamps, a division of General Electric.

“These amazing, large-scale paintings were done as advertisements, and now they’re being put on view to the public for the first time,” said Stephanie Plunkett, the museum’s chief curator, adding that “we constantly change our collections to highlight the influence that illustration has had across time and how Rockwell is a part of that great tradition that continues today.”

While the museum houses the world’s largest collection of art by Rockwell (998 original paintings and drawings in all), many other exhibitions rotate through, including, currently, “All for Laughs: the Artists of the Famous Cartoonist Course,” which was a popular 1950s correspondence course designed to teach artists to be funny; and “Original Sisters: Portraits of Tenacity and Courage,” a series of portraits by Anita Kunz that honor the contributions of history-making women.

Starting in June is “I Spy! Walter Wick’s Hidden Wonders,” showcasing Wick’s iconic photographic creations, and opening in November is “Jazz Age Illustration,” which explores popular illustration during the 1920s and 1930s and the cultural impact of that work,

Many visitors are surprised at the variety of exhibitions, Plunkett said.

“It’s a very mixed audience. Some people grew up with Rockwell’s illustrations; their families may have received the Saturday Evening Post or the Ladies’ Home Journal, and they have a real familiarity with his work. But we’re getting people across the age spectrum, lots of families with children and young adults. We had a Mad magazine exhibition that brought in an audience interested in comics and cartoons and satire. In addition, we have people who are travelers, people who may view us as a destination location.”

During the warm months, visitors can also visit the actual studio where Rockwell — who lived in Stockbridge for the last 25 years of his life — worked. The building was originally located in the backyard of his home on South Street and moved to the museum grounds in 1986. “It’s fun for people to experience Rockwell’s workspace,” Plunkett said.

The Norman Rockwell Museum is open every day except Wednesday, 10 a.m. to 4 p.m. on weekdays and 10 a.m. to 5 p.m. on weekends. Learn more at www.nrm.org.
