A pretty big part of one side of his arm but the tattoo is not on that part. I know, it's confusing, but imagine where the tattoo is and check the picture again.

The tattoo does not reach the elbow and that part of his body is hidden by the piece of armor which specifically covers that. The third tattoo is the only one that could be seen but the elbow is still below the tattoo and it's covered by the armor. What we are seeing in that picture is half of his arm, not the full arm so there is no solid proof.
