A very nice callback to his work on the series in the late 70s!
Joe Staton is one of my great favourites of the 70s and 80s era of comics, particularly for his Green Lantern work, though I am pleased to see he has managed to pull back on the more cartoonish elements of his style for this convention piece. By the time he came to illustrate Guy Gardner's series in the early 90s his artstyle was developing in ways I wasn't entirely liking... but perhaps some of it comes down to what inker he is paired with as well. A good finisher can make all the difference in the world. A shame in a way that his contributions to DC Comics are unrecognised and unlauded, but then this is nothing unique to him as the equally prolific likes of Don Heck, Bob Brown, Irv Norvick, and Dick Dillin are largely forgotten today as well.
I'm with you on this. I liked a lot of his earlier stuff and didn't like the more cartoonish later stuff. I liked his All-Star Comics and Green Lantern but Millennium not as much. I liked Guy Gardner Reborn but not his work on the ongoing. Although he did a couple of pages and pinups later on in the series that I liked. I didn't follow the inkers and they may have made the difference.
I actually have a couple of pages of Mr. Staton's original art from Green Lantern.
