I'll be posting this again in June as it gets closer to HEROESCon but wanted to show this since it was done anyway.
You can bid on this piece at the auction in Charlotte, I believe it's Friday night, June 19th, but don't take my word for it, you can look up the info on their website.
All the proceeds are donated to children's funds.
the original sketch
the "Batman: The Animated Series" backgrounds were a source of inspiration
