These are pictures of our front door. Our house is 130+ years old and this is the original wooden door. The door has an old "doorbell" (which, sadly, doesn't work) and cool blue-glass windows above it. (It needs to be washed and re-painted ... we live in a dusty, little, historic town.) Here is a view from the outside:
And a view from the inside:
The back of the door was actually faux-finished. We thought it was stained until further inspection.
