Eliza Dushku
Eliza Dushku has recently gotten her first tattoo. It's a double headed eagle, modeled after the one in Albania's national flag. She got it done during her first visit to Albania, her father's homeland, and Kosovo. It can be found on her back right below her neck.

Faith
Her character Faith has a bold tribal tattoo in the middle of her right arm.

Before Faith was brought on to Buffy, they took these promotional pics and it looks like maybe they had originally picked another tattoo for her arm instead of the one used.
