I'm not seeing anything to indicate it was pressed. I haven't seen a white "glow" before though. It's a '52 and I've seen a lot of weird stuff over the years when people jammed them into pages and the top 1/4 inch stuck out. It appears it could be the same scenario here.

I agree with previous posts though....if you're uncertain; there are plenty of RS available that may be a more comfortable purchase.
