Rivanna NF Pro Font
OTF
This font has a charming mix of the organic forms of the Art Nouveau style and the geometric forms of the Art Deco style - and it makes it work!
Nick Curtis says: "A general-purpose Art Nouveau font that has been kicking around for a while under various names. As usual, redrawn for consistency and economy of line. Named, for no good reason, after the river that flows near Thomas Jefferson’s home, Monticello."
