There are plenty of fonts that look similar to that. Linotype Zapfino Three, for instance., which isn't quite the same. There is a possibility that the sample you have provided isn't a font at all and was painted on by hand.

Thanks! I'm pretty sure it wasn't painted on, because this was an ameture graphic. That font is awesome, thanks!
