Geheimagent is perfect for writing restrictions, or permissions if you prefer. Not quite a text-font, not quite a headline-font, it’s a bit of both.

The Italic versions break up the strictness of the regular fonts. They are fast and forward and make a perfect mix with the servere upright uppercases. Try to render the font and trash it up a bit.

Cut it, paste it, it will survive. Because it has already seen everything since its origin as a prohibition sign in an industrial harbour.
