A label for what?
Anyway, I would start here: http://www.myfonts.com/search/art+nouveau/

Maybe a little unclassic, Nouvelle Vague:
http://typographica.org/typeface-reviews/nouvelle-vague/

Thank you!

Yes had looked there, thank you - looking for something unique.

Possibilities:
http://www.myfonts.com/fonts/lamatas/gaisma-latin/
http://www.francktrebillac.com/25895/88026/home/absinthe-free-font
http://letterheadfonts.com/fonts/billhead.php

Paul, if you need just the label, someone here or on typedrawers.com could do a custom lettering job for you.

Thank you so much for your help RiccardO!
