John Baichtal of MAKE says:
I’ve been admiring Jason Thompson‘s beautiful D&D maps that he drew for various classic roleplaying adventures. His sendup of A1: Slave Pits of the Undercity shows a redrawn version of the main dungeon map of the adventure, with each room illustrated to reflect the monsters, traps, and treasure contained therein. Plus, Jason includes annotations describing a theoretical adventure party’s travels through the tunnels.
