Delta has a report on running the Tomb of Ra-Hotep, the OD&D dungeon by Alan Lucien that inspired Gygax's Tomb of Horrors (and Necropolis, it seems). It was included as an extra in the reprint of the original tournament version of Tomb of Horrors, which was itself an extra with the Special Edition of last year's Art & Arcana.
