6x8 inch white paper (back of a convention flyer) hand sketched and autographed in black Sharpie by Battlestar Galactica actor Aaron Douglas (Chief Tyrol). This sketch references Season 2 Episode 9 (Flight of the Phoenix) whose main storyline featured Tyrol building a Stealth Viper first codenamed Blackbird and unveiled as Laura (after the ailing President Laura Roslin). Douglas sketched an outline of the Stealth Viper and added these notes:

Stealth Fighter

Carbon based skin

FTL Drive

Built by Chief Tyrol

The Blackbird

"LAURA"

Inscribed To Mark. Obtained in person at 2005 London Comic-Con, with photo of Douglas with the sketch, and Certificate of Authenticity from AutographsForSale.com. This is obviously a special and unique collectible for any fan of the reimagined Battlestar Galactica series.
