Billed as “the largest outdoor art show ever conceived,” a summer exhibition will span from Hollywood billboards to New York's Times Square.

Five museums — the Los Angeles County Museum of Art, the Art Institute of Chicago, the Dallas Museum of Art, the National Gallery of Art in Washington, D.C., and the Whitney Museum of American Art in New York — have joined the Outdoor Advertising Assn. of America to create Art Everywhere, a massive, interactive art campaign.

Starting this week, 100 artworks chosen from the collections of the five musuems are online for public voting. In August, voters' 50 favorite artworks will appear on 50,000 billboards and signs across the nation.

Part publicity play and part art education, the campaign follows a similar one in the UK last year. Ballot options cover works in all mediums, dating from the 18th century to 2008.

There are iconic images such as Grant Wood's "American Gothic" in the mix, and works by Edward Hopper, Mark Rothko, John Singer Sargent, Mary Cassatt, Ed Ruscha, Catherine Opie, Andy Warhol, Cindy Sherman and Frank Lloyd Wright.

“In a way, it’s a mini history of American art — and an opportunity for people to identify which works resonate for them personally,” said Dallas Museum of Art Director Maxwell L. Anderson.

Voting options are online at ArtEverywhereUS.org, with the final ballot set for June 20.
