Interesting Bird's-Eye View of the White Mountains, and the first I've seen that includes Effingham's Green Mtn. (but labeled "Mt. Green"). In 1890, it was a lot closer to Black Cap in No. Conway than it is today. Tectonic drift or something, I suppose.
There's a copy of this posted on the wall at a turnpike rest area maybe 10 miles south of Concord - IIRC, near where 93 and 3 intersect. I enjoy old maps like this.
