Mesmo Delivery creator Rafael Grampá shares a piece of artwork from an art exhibition celebrating Batman's 70th anniversary. This is the first I've heard of such an exhibition, but I'm sure more information on it is coming soon.
"Batman was the first comic character I drew when I was 3 years old," Grampá writes. "I always watched the 60’s TV series and I was totally crazy about it. This character was very important in my dream and decision to be a comic book artist when I was a kid."
