This photo most likely shows the final stage of the building at 11-13 Harvard Square. On the left,with its delivery wagons parked out front, is T. H. Dyer, Provisions. On the right, at #13 Harvard Sq., is Frank F. Seamens, Groceries. It appears that Lucius N. Danforth, a clerk at the Dyer store for two decades and at the George Joyce store there before that, has taken over the store. But the Danforth store will be short-lived: the building that exists today is about to be constructed there with Rhodes Bros. taking over occupancy.
