That leaves Spain, America and England, I think...
I like the idea. Here's a few suggestions:
England
Actually, Numitor had a suggestion for this one. I'm not sure I like it, though.
I first thought of a gothic blackletter font, but I agree we should use something like that for Germany.
Maybe a Uncial Celtic font, without treading too close to the Viking-type Danish one.
Something like:
Gael
For either England or France, a cursive Chancery font might be good, something like:
Black Chancery
An "aged" cursive Chancery:
1610 Cancellaresca
Spain
I think the Arab influence makes Spain unique. I think something like
this goes too far, but there's the Art Nouveau font,
Arnold Boecklin (which looks to me like a Spanish feel with some Arab influence, though as the Wikipedia entry states, I have been influenced by Corel's name for the typeface)
Some free knock-offs:
here
But probably a less-stylized version would be best:
Presidente Tequila
America
It's hard to come up with something uniquely "American." I was thinking of 1776 era: There's the gothic fonts at the top of the Constitution and The Declaration of Independence, but that's not very unique. The cursive script used for the text of those documents is probably too hard to read. I don't know if I like any of the Old West fonts or Art Deco fonts for this purpose.
This one spoke to me for some reason:
Puritan
France
I'm not sure I like Numitor's choice for this one, either, but my first ideas end up in the Art Deco-spectrum like he does, something like:
Parisian
See above about cursive Chancery fonts.
Maybe a Gothic calligraphy like:
Civitype FG
An "aged" one:
1742 French Civilite
I'm not sure what you mean.
He means the Rome font would use capital letters only, with V's instead of U's, like on a marble carving. Or small-caps, like the font in Numitor's post.
