That's what I thought, too, but the "EXIT" sign above his head reads correctly. I know Reagan was right-handed, so it's interesting he would site a rifle left-handed... Or, maybe he was striking a pose for the camera and so he is holding the rifle unnaturally. Or, maybe he was truly amidextrous. My Dad was like that.
