Angie,
I cannot speak for how the catalogers will see this, but might it be hard to assert that it is one of a kind?
The process is not so unusual: https://www.loc.gov/maps/?dates=1100-1199 and https://en.wikipedia.org/wiki/Stone_rubbing .

[log in to unmask]">Hi have a map that is a rubbing from a stone. So, it's a one of a kind, hand done rubbing but a reproduction of a map on stone.
So is it a manuscript or is the rubbing method simply the printing process?
Help.
Angie
