Very cool idea, perhaps you could talk to my wife, I've got a birthday coming up!
You could reproduce a famous recipe, for instance George Washington's "small beer.", While Washington may not be your cup of tea, I'm sure you could find others. Another idea would be to print a high quality photo of brewing instructions found in Egyptian hieroglyphs or perhaps a sumerian tablet.
Good luck finding it, I would love to see what you decide on.
