Revolution #1 has been released and a couple of the excellent variant covers have been produced by Adam Riches, who is well known to G.I. Joe fans as one of the artists of the Figure Subscription Service cardbacks.
He has done a couple of fantastic variant covers, and he has listed some of his original art on eBay. One of the auctions is the Optimus Prime/Scarlett action figure cover and it looks really great.
Any G.I. Joe or Transformers fan should check out his listings on eBay now and get these great pieces while the getting is good.
