Colony, Prison Break & The Walking Dead fans, you are bidding on a hand signed 4” x 5.25” signed postcard of Sarah Wayne Callies as Katie Bowman from USA Network’s hit show, Colony.

Sarah was kind enough to donate this photo directly to Zombie Leader’s Comic Art for Leukemia and Lymphoma (CALL) Auction at a past Rhode Island Comic Con. (See comic con photo—which is not included with the signature but to show provenance.)

Proceeds of this auction benefit The Leukemia and Lymphoma Society CT-WHV Chapter. Thank you for your support in eradicating blood cancers.
