All the art – cover and interior – in Saga of Old City is by Clyde Caldwell. I love how the old school TSR books had illustrations in the interior, really adds flavor to the book. This isn’t random stock art. Each is tied to a scene in the book.
It was Gary Gygax’s first Gord the Rogue novel. Several more would follow, even after Gygax left TSR.
