Recently I did some sketch cards for the New DC 52. It was awesome working on the set but I wish I could have drawn them in their classic costumes as well as the new 52 ones. The one character I wished that the most for was Etrigan The Demon. What a great character and full on Kirby! It was a while into my comic collecting and nerd training before I learned that Kirby creator not just for Marvel but for DC as well. There is still tons of his DC work I haven't read yet but The Demon is one of my favorites.
