Isaac’s paintings, actually tremendous graphic artist Tim Sale’s paintings, going up for auction. NBC has decided to auction some full-size autographed limited editions prints of original paintings. The first auction will start at 6 p.m. PAC on March 26 and close at 12 a.m. PAC on March 28. (via TvSquad)

Vivi Zigler, Executive Vice President NBC Digital Entertainment and New Media, announced in a press release that NBC was proud of this event as it would not only allow fans a chance to own a piece of the hit show but also benefit the Epilepsy Foundation. This foundation was chosen because Heroes’ cast member Greg Grunberg is highly involved with it since his son Jake suffers from epilepsy.

NBC.com will hold two different auctions. Each auction will feature two full-size autographed limited editions prints and drawings of artwork used in the show, which includes “Exploding Man,” “Eclipse,” “Claire on the Stairs” and “Hiro and T-Rex.” The first auction will start at 6 p.m. PAC on March 26 and close at 12 a.m. PAC on March 28. The second will be held at the same times but from April 2 to April 4.
