Something crooked on the set of Hardball?

Take a look at this image. It’s a direct screen grab of “Hardball” with two horizontal lines added to show that the textural lines, constitutional text and “Hardball” logos found in the dura don’t seem to be straight.

This could be being caused by the fact the camera shooting Chris Matthews is off-angle. However, this type of framing typically causes a perspective effect rather than making the background look off-axis.

Could the camera be crooked? The floor? The set? Who knows. Most likely it’s just an optical illusion, but it’s the kind of thing that once you noticed it, it bugs the heck out of you.
