Here is another black and white David Trampier illustration, a full page treatment of an adventuring party and a Giant Spider. This illustration appears in the 1977 Advanced Dungeons and Dragons Monster Manual.
I love the off-camera character, on the right side of the illustration, pointing at the giant spider, with the halfling beside him displaying a stunned or horrified look.
The rest of the party is clearly oblivious to their imminent doom, instead focused on some other off-camera dungeon feature, and only vaguely interested in the sticky web barring their way, with the fighter lazily attempting to cut through the strands. Or perhaps the magic user and dwarf are cautioning the fighter against or encouraging him into using the torch on the web.
Note that the fighter is not your buff, plated superhero, but looks to be rather modestly furnished with a backpack, sword and scale or chainmail armor. The dwarf seems to be wearing splint mail and has a shield strapped to his back. I think its also interesting that the fighter is the party member carrying the torch. Did it get passed to him just before the events depicted in this picture?
Another fine example of implied narrative from Tramp. How will this scene resolve itself? Will the party be surprised, and the fighter felled by the poison of the Giant Spider? Or will they notice the spider lurking above, and succeed in defeating it and collecting its treasure?
