White Box Fantasy Medieval Adventure Game

This is used copy (near mint condition) of a retro clone game which basically provides slightly-cleaned-up rules for the Original Edition of DnD (which came out in a white box in 1974). Initiative is a d6 (one die rolled by the party leader and one die rolled by the DM), all weapons are d6, race is class--its got all the key elements that gave the original DnD its flavor.  The book itself is the size of a small paperback, about 142 pages long.
