I like OSRIC’s character sheet, and even though it’s missing some important fields for AD&D 1e and feels more like a B/X sheet, it’s still familiar enough to OSR players and simple and clear enough for players new to the game.

For players who really want to get into AD&D 1e with all the rules though, nothing is better than TSR’s official Player Character Record “goldenrod” sheets.

UPDATE: I no longer like OSRIC’s character sheet, especially for AD&D games. I figure that if I’m going to run a crunchy game, I need a crunchy character sheet to go with it.
