--Ok, so they released the cover that Greg Land drew for the Marvel adaptation of the original Tron film. I decided to have some fun and see how quickly I could tear it apart. In under an hour, using Google Images, I quickly found several of the reference images that he probably used. I've attached the original cover and my photoshop edit, showing the ref pics:Original cover
Kevin Flynn & disk
Lightcycle (and the Grid lines up!)
Guard (not exact)
I'm pretty sure he recycled the Light Cycle twice, and the Guard looks recycled both times, but his pole moves. I could not find a reference for the Recognizer, though it looks fairly geometric and inaccurate to the original. Thanks again for an awesome blog!
It seems like he did indeed, like he often does, use Google Images for many of the pics. Although (to be fair) since its a MOVIE ADAPTATION of the film, I can let the photo-tracing slide with this one... but its still fun to discover his "process".
