Old plats for wall art mounted on linen from old plat books

I have a collection of hundreds of the old plats from either a BLM office or NARA that were found in a house that was being demolished.

There are some very old copied plats dated from the 1860s all mounted on the linen as per the process in the day.

I'll post a few for reference to see what I'm describing, and not sure what people are going to or willing to pay for them.

I've started framing the ones I've looked at, majority are from the southern border of Colorado and New Mexico, some central Colorado and then the northern border of Colorado and Wyoming.
