I think this is just an incredible coincidence. at least from the sneak peak of it. I did a painting for a gallery show a few weeks ago of a masked Cthulhu Luchador. which looks like a similar concept for Saturdays shirt. Crazy how sometimes artist in totally different parts of the world can have similar ideas and concepts. i haven't seen the full design so it could be something else entirely. just for fun here's the painting I had done (Not a great picture but its all I got):
too bad artists, believing the other artist stole from them, often start calling each other names (there have been various accounts of this here on TF and elsewhere)
looks good, thanks for posting. what's that in the background? I mean: material-wise
