Flash Rogues Gallery jam - Captain Boomerang, Mirror Master & Captain Cold by Budd Root & Buddy Prince

My original concept was to have just the two captains drawn by the two Budds. Buddy Prince started off by drawing Captain Cold and the layer of ice below him at the 2013 Heroes Con. Budd Root took the drawing home and added the other two characters plus the lettering. Since the Mirror Master is my favorite member of the Rogues Gallery, the deviation from my original plan was a pleasant and well received surprise. Plus I really like Budd's "The Flash Must Die" lettering.
