1910 Whitney's Pocket Guide Street Map of Portland, Me. railroad

This is a 1910 Whitney's Pocket Guide Street Map of Portland, Maine and vicinity. It is about 12.5 by 15 inches in size, and is folded to 2.5 by 5 inches. It includes streets, trolleys, and railroad lines. A 1921 version has a cardboard cover and the index printed on separate pages in a booklet format. This version appears to be the original printing with the street index printed across the back of the map. Advertisements include George W. Barbour Jeweler, Caine Optical, Wallace's Greenhouse, and The Flower Shop on Oak St.

As shown, there is a separation along the seam of one panel, and there are pinholes at some intersections. It was also folded incorrectly to show an advertisement instead of the map name.
