This colorful bird's eye view of the New England coast from Boston Harbor to Portland, Maine shows the various kinds of train and steamship line connections for summer tourists wishing to reach their vacation destinations in Maine. The map key explains that the transit routes are for the Atlantic Shore Line Railway, a Maine electric street car of sorts, the steam railway line of the B&M R.R. and the Southern Maine Steamship Line with connections to the Atlantic Shore Line Railway.
The landscape and topography from Boston Harbor and north to other towns in Massachusetts and in Portsmouth, New Hampshire to Maine are shown in a pictorial style characteristic of bird's eye views that invite the viewer into the scene. We see some of the city buildings in Boston and the town centers of Newburyport and Amesbury, among others. Ogunquit is highlighted with its long sandy beach north to Wells, Maine. Small ships are drawn along the steamship route from Boston Harbor to Portsmouth, New Hampshire and up to Cape Porpoise in Maine. Other connecting electric lines from Hampton Beach in New Hampshire make a loop to Exeter, New Hampshire. A connecting electric line runs from Saco to Portland.
This piece is not dated. It can be dated within the range of operation of the Shore Line Route that was turn of the 19th century into the early 20th century. I have found no published examples of this bird's eye view of the Shore Line Route.
