IIRC someone released information publicly online in the last year or two enabling someone to publish an RPG product with the same look as standard late 1st / early 2nd Edition Advanced Dungeons & Dragons adventure products (you know, before e.g. Planescape's weird graphic design, Ravenloft and the Middle Eastern setting).
This info went beyond just specifying the fonts TSR used back then (info available many places online), to covering column layout and width, heading font sizes, etc. IIRC all this was shared in 1 or more files linked to on at least 1 website.
I cannot find this stuff now using various search strategies. Where is it now available?
PLEASE DO NOTE: I am only interested in resources which are legal for use when NOT publishing community content for (A)D&D (e.g. under Wizard's OGL).
