The "original" Dungeons & Dragons created by master magicians Gary Gygax and Dave Arneson. It was published in 1974 and is a bit of a far cry from the D&D that was yet to come. But it's amazing to see this early take on the rules.
There were just three classes included: Fighting Man, Magic User and Cleric. Four races: Human, Elf, Hobbit and Dwarf.
The game was based on the miniatures wargame Chainmail and it borrows heavily from those rules.
