Very cool 5-arm telegraph pole line leading from Boston to points south (eventually NYC and beyond) that I very fondly recall seeing as a kid with my nosed glued to the back window of my family's car :-) I believe this photo was taken in Dedham, MA with Route 128 (also aka I-95) overpass in the background. This line had zillions of insulators on it, almost all were commons with decades of train smoke seemingly-permanently cooked on them, LOL. The unique greenish color of the old copper patina of the many tightly-strung telegraph wires from pole-to-pole extending into the distance also was a terrific sight to see! Most sections of this line were removed by 1968.
