As a designer, I also need more information to respond.
There are posters and handbills from the mid-19th century that were frequently done in decorative woodtype that are highly distinctive and very American. These are the familiar "Wanted!" posters of the American West, railroad "travel" posters and theatre production posters. But as we move into the 20th century, Art Nouveau, Art Deco, Art Moderne, Bauhaus and other styles become more international in their scope and choices of fonts.
So, can you tell us more what you're looking for? And what time period?
What you'll be using them for makes a big difference. If you're making
a fourth of July greeting card or party invitation, you wouldn't want
the same feel as you would if you were printing the Congressional Record.
Yes, sorry I should have given more info. I am designing a book cover for a book which is about why America deserves its superpower status. So it looks at American history and I guess all time periods really. So if anything I would need something which symbolizes America as a whole or perhaps its power and world status! Maybe nothing like this exists but thought I'd just ask anyway.
I wonder if using Jeffersonian penmanship would do the trick, if it looks at History. I'm not sure there is a font based on the script, but a good letterer should be able to duplicate the writing of the Declaration of Independence.
