Are you one of those people who checks the seat pockets of the chair in front of you when you get on a plane?

Well, you could end up being the person who finds Brian Stelfreeze’s sketch of Catwoman on a sick bag.

The Marvel comic artist tweeted of photo of his artwork that he left on the plane, saying: “If you are flying from Adelaide to Sydney in Australia today, Brian left this hidden art for you to find.”

Stelfreeze has created illustrations for most American comic book publishers, but recently he was behind the drawings in the 2016 revival of Marvel’s Black Panther.

Unfortunately for fans, Stefreeze didn’t specify the airline he was flying with.
