I reported a couple of months back that Disney had green lit the animated series Star Wars Rebels, which is due to debut in 2014. The series takes place between Star Wars: Episode III - Revenge of the Sith and Star Wars: Episode IV - A New Hope and chronicles the birth of the Rebel Alliance. At the recent Star Wars Celebration Europe II gathering in Messe Essen, Germany, animator revealed the logo for the show (above), plus some concept art.
According to /Film the piece of concept art features a ship, called Ghost, "a cross between a B-17 and the Millennium Falcon" and will act as a base for the rebels.
Star Wars Rebels will be shown first as a one hour special on Disney Channel before going to series on Disney XD.
