"Basic/Expert" Dungeons & Dragons by Moldvay/Cook from 1981.

Tom Moldvay revised the "Basic" D&D game in 1981. It came in a red box and featured the B2 Keep on the Borderlands module. It came with dice (and a marking crayon!). These rules handled levels 1-3. David "Zeb" Cook wrote the follow-on "Expert" rule book (another boxed set) that expanded the game to levels 4-14.
