nice job rgilfert! I did something similar. I bought two topo maps on-line and brought them to a framer who cut them and pieced them together to cover the area around Hills Pond. Like you, I used acrylic and a light weight frame so that it could be easily taken down off the wall for quick reference. The old topo maps name all the peaks, their elevation and some hiking trails.
Here's a link to the UNH collection of on-line topo maps by town with most towns having a 1909, 1929 and 1957 version of the way things were back then
