Jess, an artist in Indianapolis, redrew the iconic Starbucks siren as the twelve incarnations of the Doctor (minus the War Doctor, of course) as well as the villainous Time Lord Harold Saxon, AKA The Master. She sells them at her Etsy shop. You can view more of her work, including more Doctor Who and Sherlock fan art, at her DeviantArt page.
