Most likely the phone company that built this line along this dusty road used local trees for poles. This probably was not the Bell System standard at the time! Thankfully (for us ICONers) lots of independent (aka Ma and Pa) phone companies operated in rural Maine as well as in other New England villages and towns. The images of how they built their phone lines from simply just whatever might have been conveniently available at the time certainly adds lots of "personality" to their poles as we look back. In other words, it seems like no two looked alike ;-)
