I'm looking for a font like Zamenhof for a project I'm working on, but would prefer not to have to purchase the font.
Anyone know of a similar typeface?
Look at Intro Inline, free for personal use http://www.fonts2u.com/intro-inline.font
There are a bunch of free fonts that imitate the "Jurassic Park" font (which is actually Neuland Inline - based on Neuland, a commercial font designed in 1923).
One is African font by Allen R. Walden (freeware):
It's hard to find much information about where it comes from but it at least doesn't look like it's an exact copy of Neuland.
