>>27661297It's a guide for third-party advertisers about what they should and shouldn't do when making Pokemon merchandise and advertisements. Some anon's roommate worked at an advertising company that was throwing out a bunch of old shit, so he happened to grab the thing before they trashed it.
It has all sorts of interesting guidelines, like "don't mix TCG, Anime, and game-specific art, but you can mix any of them with generic Pokemon art" and "don't show Pokemon floating around in space, unless it's one of the ones that's supposed to be in space".
