DC unveils another 75th-anniversary variant cover, maybe?

This week DC Comics has been unveiling some of the variant covers they’re doing in honor of their 75th anniversary. Each cover promises to be a “classic” cover redrawn by a “big name” artist, with the first two this week being Batman #700 by Mike Mignola and Superman #700 by Eduardo Risso.

Today DC’s The Source blog posted the above cover, a remade — and re-colored — version of the cover to Green Lantern/Green Arrow #76 (you can see the original after the jump), which was part of Denny O’Neil and Neal Adams’ classic run on the book.

Unfortunately, they don’t list any additional information about the book, so while logic may dictate that it’s another in the variant cover series, I guess it could be something else. Any idea who the artist is?
