The central portion of the page is clearly a rip off of the famous "Bird's Eye View of Lake Winnipesaukee, NH" that I have seen numerous dates associated with (e.g. 1903, 1909 , 1925, etc). My map was produced by the "New England Map Company" in Somerville, MA and the apparent value added to the more famous depiction was the addition of boat routes, depths, sea plane landing sites, fishing locations etc. Additionally other pictures and charts were added around the edges of the chart. Most helpful in dating the map is the inset showing NH Highways for there is no evidence of the existence of any piece of Route 93. I know that the first segment of Route 93 that was opened was in Concord in Dec 1956 so this document obviously pre-dates that. Has anyone ever seen a copy of this chart before, and if so, do you have any info more specific as to the date that it was produced?

Sea plane landing sites for Winter Harbor wouldn't have appeared until ~1949.
