Stage veterans Annette Bening, Julianne Moore, and Mark Ruffalo are among the artists who are participating in an online auction sponsored by the Clothes Off Our Back Foundation, which raises money to support children's charities.

The performers have all autographed a T-shirt which they wore in the Oscar-nominated film The Kids Are All Right, including a charcoal-colored Coachella brand graphic T-shirt autographed by Bening; a forest green-colored Free City T-shirt with orange hummingbird autographed by Moore, and a gray Calvin Klein T-shirt autographed by Ruffalo.

Other items in the auction include a gray cotton T-shirt with motorcycle imprint autographed by Mia Wasikowska and a light blue Ben Sherman T-shirt autographed by Josh Hutcherson, the actors who played Bening and Moore's children in the movie.
