From the announcement:
The original Dungeons & Dragons boxed set was published by TSR, Inc. in 1974 and was the very first roleplaying game, introducing concepts that have persisted throughout later editions. It included three small rules booklets in a white box.
This deluxe, premium reprint of the original "White Box" features new packaging and includes the following seven booklets (plus, reference sheets):
Volume 1: Men & Magic
Volume 2: Monsters & Treasure
Volume 3: Underworld & Wilderness Adventures
Supplement I: Greyhawk
Supplement II: Blackmoor
Supplement III: Eldritch Wizardry
Supplement IV: Gods, Demi-Gods & Heroes
Each booklet features new cover art but is otherwise a faithful reproduction of the original, including original interior art.
