The f definitely looks like a custom edit...looks like it's been edited to make it into an 8, or infinity symbol. The dots on the i's* might be custom edited too.

As for font, I dunno. It's too slanted to be Book Antiqua, although that makes a close approximation otherwise. Close, almost certainly not exact. I'll leave this for the experts.

* Note: the only case in English where you're allowed to pluralize with an apostrophe

okay, I scanned through my system fonts again and have come to the conclusion that it's Lucida Calligraphy....though obviously not the "f".

Ah, that makes sense. Well there you go :P
