No idea, its an outline of a famous superhero, though it doesnt show him, nor has any copyright!
Ive edited a lambo picture to remove any badging and tried that. Issue is it take 12 hours + to reply, so if it fails im screwed 
I suspect that one will fail as well. The outline still forms part of the design as it'll still be recognisable, which I think would be in breach of the copyright. Having a look on the net a lot of people are getting their images rejected, so I guess they're being super tight.
Both the ones I did for me and my wife were accepted though, so happy times
