Fred Fields modeled his cover art for A Paladin In Hell (1998) after a section of the classic full-page art of the same name on page 23 of the Player’s Handbook (1978), drawn by David C. Sutherland III.
Fields was far from the only artist to draw inspiration from this classic Advanced Dungeons & Dragons art. Hack & Slash blog shows a number of examples.
The two Paladins are much alike, even down to fine details.
The Devils are quite different, though themes are retained, such as the barbed elbows, knees, and continuous barbs.
The Barbed Devil
Let’s compare Sutherland’s Barbed Devil with the illustration by another great D&D artist, David A. Trampier in the Monster Manual (1977), page 21.
The two portraits are very consistent: Head horns, hook nose, fangs, knee and elbow barbs, tail spikes.
I don’t know which came first. The Monster Manual predates the Players Handbook by a year, but that may or may not be relevant.
