Well, the GP was fairly easy (though, it's probably not perfect, since it's pretty hard with a blurry reference like that) but the X one I could probably try to approximate but it would probably be far from what it actually looked like with this picture as a reference - I can't even read the text (if I had to guess, I'd say it says: "NO ONE UNDER 17 ADMITTED / AGE LIMIT MAY VARY IN CERTAIN AREAS" but I'm just guessing).

Thank you Harmy! This would go great with THX 1138, as it was originally rated GP. :)

I can dig up a better screenshot of the X card if you need it.
