This is the character biography card that accompanies the Battlestar Galactica replica Starbuck dogtags. It, along with replica tags for Apollo, Adama, Athena, Helo, Tigh, and Chief Tyrol, can be bought from Quantum Mechanix for $19.95 each, or the full set can be yours for $119.95.
Quoting from the website:
Each character dog tag has been recreated in metal, plated in bronze and weathered to exactly match the tags as seen on the series. All dimensions are taken directly from screen-used dog tags. All serial numbers are screen-accurate, as well. Each set of dog tags is packed securely in a Battlestar Galactica-themed blister pack and features a matching neck chain and collectable character biography card with a description of that character's story so far (as of the end of Season 3).
If you're a fan of the show, I encourage you to buy a pair. If you're a fan of Palette, I encourage to you buy a bunch, because the more profitable they are, the more likely it is that QMx will be able to have me do more freelance projects (or, Lords of Kobol willing, maybe even hire me full-time.)
Support your local Geeky Goth Girl, and all that. ;)
EDIT: If you're not into wearing someone else's dogtags, you can always order a customized pair with your name on them.
