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.
There were a couple of SIlver/Bronze age artists whom I was generally no fan of, but who when they had the right assignments, completely blossomed and produced magnificent work. For the most part Staton's cartoony style didn't appeal to me (and certainly not on Green Lantern), but his work on the JSA and on E-Man are among the best of the era.
