NBC's hit-drama Heroes is living up to its name by teaming up with NBC.com to auction artwork by renowned graphic illustrator Tim Sale exclusively on NBC.com with two separate auctions to begin on March 26 and April 2. All proceeds will benefit the Epilepsy Foundation.

"We're so pleased to be able to offer this opportunity to the dedicated fans of Heroes," said Vivi Zigler, Executive Vice President NBC Digital Entertainment and New Media. "We're especially proud of this event because it not only gives our users the chance to own a piece of the show, created by the incredibly talented Tim Sale, but it also benefits a worthy organization, the Epilepsy Foundation, which works so closely with Greg Grunberg."

Each week's auctions will feature two full-size autographed limited edition prints and drawings of artwork used in the show. The list of artwork includes "Exploding Man," "Eclipse," "Claire on the Stairs" and "Hiro and T-Rex." Bidding will go live on March 26 at 6 p.m. (PT) and will close at 12 a.m. (PT) on March 28. The second auction will go live at 6 p.m. (PT) on April 2 and close at 12 a.m. (PT) on April 4. NBC.com has partnered with San Francisco-based Delivery Agent, Inc. to power this auction.

"We are thankful that Greg Grunberg, inspired by his own real-life hero, his son Jake, who has epilepsy, has joined with us to increase awareness of epilepsy," said Eric R. Hargis, President and CEO of the Epilepsy Foundation. "With the help of Greg, those like him, and partners like NBC, we can end the stigma associated with epilepsy in this generation."

Epilepsy can affect anyone, anywhere at any time -- especially in early childhood and in the senior years. More than 3 million Americans of all ages live with epilepsy -- about one in every hundred people. The Epilepsy Foundation (www.epilepsyfoundation.org) works to ensure that people with seizures are able to participate in all life experiences; to improve how people with epilepsy are perceived, accepted and valued in society; and to promote research for a cure.
