If I were to try removing the pencil marks can anyone recommend a type of eraser?
To remove those marks most safely you need two tools: a fresh art gum eraser and an erasing shield. The latter is an inexpensive metal device that was used by a draftsman in days of yore. I have one around someplace, and may try to find it and scan it if you need to see one. or just Google it. As you can tell, I use it all the time with my stamps. [Not.]
First ascertain that the paper is strong enough to withstand what you are about to do (per the suggestions below) I would not try even this on an unsized or lightly sized paper, such as India paper.
With the shield properly in place, bear down on it against the stamp, and then in the open slot
gently scrub in small strokes everywhere the marks are found, letting the eraser crumble to nothing as it removes them. As you get near the paper edges make sure your strokes start on the stamp paper and
always move toward the edge never away from it into the stamp. When you have cleaned a spot as much as you wish, move the shield and start over at another part of the problem. DO NOT slide the shield around as you are running the eraser on it.
This is about as gentle a low-tech solution as you will find for your pencil marks.
