This 1996 image depicted a man seated in his motorized wheelchair just outside his home, and was about to pass inside through his opened front door, while his dog was awaiting his arrival. Note that the smooth concrete pathway, which connected the front porch with the driveway, was flat, and level with the smooth, brick-surfaced porch, and that there was only a very slight elevation at the front door threshold. Also worth noting, was the presence of a floor-to-ceiling sidelight window adjacent to the door jam, the levered door handle, and a roof covering the front porch area, which is suggested in order to facilitate entrance to all, but especially, to the mobility-challenged.
