I was cleaning out an apartment at work, and the tenant left this DOOM poster behind. They lived on a school campus, and were fired, so they left in a hurry.

I know it's not signed by the man himself, but I can't figure out whose signature is on the bottom right. It's probably the artist, but I can't make the name out. If I look really close, I cannot tell if it's real or part of the print. The poster itself is clearly a print, but I can't rule out the signature. I took the poster out of the frame, and there's no writing on the back of it.

Either way, it's going up on the wall. Any help would be greatly appreciated.
