Interesting that absolutely no one mentioned that there is no place for "TO HIT ARMOR CLASS" numbers: believe it or not, that's kinda important in a pre-THAC0 system.
Oh, and it's missing SAVING THROWS as well -- you might need those if you actually played AD&D 1st ed.
It's got a large area for thief skills, "notes," and "misc", because everyone can just use those during melee or while under magical attack?
Is there supposed to be a second page?
A previous reviewer claimed "This character sheet is, from memory, an almost exact reproduction of the kind I used to play AD&D back in the late 1970s and early 80s."
No it isn't -- the TSR 1st edition character sheets looked absolutely nothing like this. Nothing in the 70s or 80s (or 90s) looked anything whatsoever like this sheet.
The dark borders are pointless, and likely to use a dollar's worth of toner per sheet.
Compare this to the sheet in OSRIC, which has places for every essential piece of information imaginable, even places for armor class with various armor, shields, etc added. And Saving Throw numbers and "To Hit Armor Class" from -10 to 10.
Alignment diagram in the bottom right doesn't help me know what I need to roll to hit or save. Really a tremendous example of style over substance.
