Detroit Fanfare is this weekend, September 24-25, and TMNT co-creator Kevin Eastman is a special guest.
While any convention with Kevin as a guest is a good convention, this convention is of particular note because Cover L of IDW TMNT #1 will be on sale, and Kevin will be sketching on it free of charge.
Here's a little shout-out from Kevin to Con-goers:
And in other Kevin news, he is currently selling the original art for his IDW TMNT #2 variant cover on eBay. Go here to join the bidding war. Good luck!
