Ellis's art is the three day badge. I also saw it as today's one-day badge. As far as I know it is the only badge save the staff badges (mine, yay me!). I came late today to the Fest and when the registration czar was printing up my wife's badge I told him whose art it was. He said when he shrunk it down and saw how good it looked badge size he decided to use it as the main art. Prizes for doing a badge can only be redeemed in person at the 2015 Comic Fest.
