This subscriber route was lined what I like to call "stick" poles. Back in the 1950's when I was a little kid I recall seeing some rather primitive lines like this in service while on family trips through northern New England. This kind of pole line stuff has always remained as my very favorite ;-)

No doubt the independent, local and "Ma-and-Pa" phone companies decades ago used whatever was available for line construction. Including used/recycled stuff, local trees skinned as poles and other non-standardized, non-Bell architecture that certainly made their lines unique in appearance ;-)
