Welcome back to the twelfth of Convention Sketches!

We feature a convention sketch here every week.  We’ve got a whole pile of our own, but we want to see yours, too. Email us convention sketches you want to show off and let us know what website you’d like credited for it.  (bigshinyrobot(at)gmail.com)

This week we bring you a Batman sketch from Dick Giordano from DC Comics fame!
