Nice find, Uzo. I was thinking it was just a coincidence, with all the Conan art out there. But if you look closely at the ripples in the muscles and the shadowing on the back, it's just too similar.
And don't forget the Simon's Quest artwork's likeness to that Ravenloft novel (or whatever it was), or the Metal Gear/Kyle Reese and Contra/Schwartzenegger & Stallone ripoffs. It's not like Konami never ripped off their artwork before.
