. . . who might consider erasing the other signatures (assuming they too are signed in pencil) around the difficult autograph, inorder to enhance it.

I have yet to do that, but I have been tempted. But I decided the risk of damaging a truly difficult autograph was just too high. And for a less difficult autograph, why bother.

I suppose it's similar to the choices someone contemplates with regards to removing signatures from a multiple signature baseball inorder to display it as a single-signed example. Some justify it as OK, as long as the modified ball is for one's own enjoyment. But what happens when it's time for that ball to move on to it's next owner? Some facts just have a way of being forgotten, or lost to time.
