Calamity Jane by Nick Curtis is a free Art Nouveau display font with a languid, turn-of-the-century swing. The letters lean on long, whiplash curves and airy spacing, mixing very slim strokes with broad rounded forms so the font feels elegant, a little theatrical, and unmistakably retro.
It fits poster titles, boutique packaging, cafe menus, book covers, and film title cards where a free font can bring period flavor without looking dusty. Use it for short headlines or monogram-like initials especially, because those sweeping curves and delicate joins give a few words plenty to work with.
