One of the most clever things Joseph Goodman did with his line of Dungeon Crawl Classics, beyond just mimicking the graphic design of classic TSR, was to hire the actual artists who illustrated D&D products in the 70's and early 80's.
One thing that kind of surprised me, is how much I still like Erol Otus' work. The new stuff he's done are just as good if not better. True, it is hard to compete with the nostalgia the old stuff evokes, but it still brings that same sense of weird wonder Erol Otus is so good at.
Since 4th edition D&D came out Goodman Games has changed the basic graphic design of Dungeon Crawl Classics. While I understand the reasoning, I do miss the old style.
