I just downloaded the OSRIC Player’s Guide, with art (and editing) by Steve Robertson. On Page 7 is an homage to the two dwarves vs. snake image from p. 13 of the AD&D Player’s Handbook. It looks like in OSRIC, the snake won the dispute…
OSRIC is essentially a retro-clone of AD&D, and the Player’s Guide is a collection of all the rules required for the creation of PCs. It’s available from RPGNow as a free pdf download.
(BTW, the header art for the Dwarven Glory gameblog is taken from p. 89 of the HackMaster Player’s Handbook. Unfortunately, there’s no signature on the drawing, so I’m not sure of the artist.)
