go to myfonts.com and type in "nouveau" or "art nouveau" in the window at the top right, you'll see lots of choices.

You need more than a font to make it work. Look for a Dover book on Art Nouveau for borders and other marks and search the web

Look up Alphonse Mucha, the king of Art Nouveau, for colors, styles, etc. Lots of flowery stuff and colors that came back into vogue in the 1970s. Also look up Vienna Secession and Jugendstil.

A couple of "art nouveau" fonts I can think of: Auriol, Desdemona, etc...

Don't confuse Art Nouveau with Art Deco.

Tanks everyone! Ive found an ok headline font now. But still looking for the text font, the serif. Does anyone have a clue which typeface they use on the front of "The Yellow Book"? Or a similar face, used in the same period. Would realy appreciate your help.

Petter, if you could show us the typeface you have decided upon for the display I think we'd know which direction on a match for the text. I'm not sure using something like this as on THE YELLOW BOOK is art nouveau enough.

I found a font called KOLO LP, which has a clean nouveau look. It feels a bit hand drawn. The text side of the menu will have a frame, similar to the one in the picture that I have uploaded. The other side of the menu will be decorated with an rather typical nouveau illustration (inspired by Alphonse Mucha).

Is KOLO LP a good choice? If so, what would be a nice typface match? Should go with a face like BELWE or perhaps JENSON, SOUVENIR, LTC FORUM TITLE or ELPHINSTONE. Hmm, I´ll think I need some guidance.

Perhaps you could do some exploration with all of your ideas and post those. Once you have worked with all combination you might have new thoughts.

I think KOLO is more Arts-and-Crafts than Art Nouveau. To me, it's not organic enough to be Art Nouveau. It feels more C.R. Mackintosh/ craftsman than Mucha/Studio/Paris.

ELPHINSTONE is too ... too ... calligraphy.

BELWE has potential for content, and arnold-boecklin may work for display?

But -- I don't think anyone does it better than P22 Art Nouveau

Gee, I see Kolo and all I can think of is Benguiat Sans -- that cap A does it every time....

Have you checked out Auriol, as suggested by BradB, above? It's from 1901, very authentic! :-)

There is also Absinthe, a more recent typeface inspired by that movement.

I'm liking Auriol too.
However, I think that for a menu, ya gotta have some of those lovely borders as in the sample you show, so it's really a question of integrating the type with the style of the border.

Windsor (Light is very classy), Korinna, and Souvenir have that "triangulating the circle" art nouveau shape.

For another tack, Advertiser's Gothic.

Auriol is gorgeous, especially if you have the complete family. It works amazingly well at small sizes too. Great suggestion.
