This canvas art displays an image of Peter Parker AKA Spider Man, its a still taken from the movie Avengers: Infinity War.
In this image Spider Man is doing one of his classic Spidey poses. His new tech suit truly compliments the pose and he seems to be on top of something while trying to maintain his balance during the battle and keeping his attack mode on. The background displays some sort of a gigantic stairway building which looks like its not from earth. Behind Spider Man we can see some yellow sparkly circle which is one of Dr. Strange’s magic tricks he uses to create inter-dimensional portals.
