Interesting Hobbit

It really does look printed, doesn't it? Could be stamped on; don't know why, but also a possibility.

My copy of the same 1975 printing does not have a castle on that page, looks to me like the original owner had a home printing kit and stamped that in.

Yeah, I think it is stamped. Paper colouring is a bit different near the castle too.

Saw this one a couple of weeks ago. My assumption was it was just an ink stamp. Can't really see what else it could be.
