Can Anyone Help Date This?

[rgilfert]

For quite a few years I have been collecting antique maps of Lake Winnipesaukee and the environs (e.g. Navigation Charts, USGS Topographic maps, Geologic Maps, etc). Recently I came across and purchased the attached folding map and I am having difficulty dating it. 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?

rgilfert, Could you post some of those photo's from around the edges. They could help date the map.

Thanks, Just Sold. Attached are close ups of the pictures/maps on the left and right sides of the lake map. I scanned at 600 DPI but the resultant files were huge (9 to 12 MB) so I compressed them so as not to get in trouble with the web master. Hope they are legible!

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

My map definitely shows two landing strips in Winter Harbor (I don't know whether you can see that in my pictures or not because the resoltion is pretty poor). So it seems that the date of my map is somewhere between 1949 & 1956...which is way closer than I was 3 hours ago (when I would have bet that the map was from the mid-1940s). Getting closer. Thanks! Anything else??

My 25-year-old Navigation Chart by Duncan M. Fichet (in Duncan green) shows three seaplane landing strips. :confused: The year 1949 was approximately when Wolfeboro's Little Airport (http://www.winnipesaukee.com/forums/showthread.php?t=2409) had first set out its dock and seaplane ramps on Winter Harbor. Your map could still precede that year.

I'm not sure "resolution" would help this old computer, as determinations of colors—especially blue—have gone missing...see what I mean? :emb:

:look: The New England Map Co. could still be in business, as one is listed in the Yellow Pages—online:

The images of the Mount Washington show the raised wheelhouse that was moved in 1947.
