Dolphin - Conventionless Convention Sketch #22 April 17, 2015 Dolphin © DC Comics Fun fact, I drew Dolphin in Aquaman #3 about 100 years ago. :) You can even pick up that comic for 99¢ on sale on Comixology this week. Ignore the cover credits though. I didn't draw it. Ink on 11" x 17" bristol board.
