Vintage Door Knob @ Equation Boy/Man's House

Have been here for more than 15 months and never paid much attention to this doorknob before Halloween this year.  That's when I spent a bunch of time out on the front porch of Vic and Equation Boy/Man's house handing out candy.  In fact, I don't think I've sat in that front porch ever.  

Their house is old - not sure exactly - but likely the early 1900's or 1910's or 1920's.  And the front door *has* to be original.  On it, is that knob.  And, it is a beauty and one of the relics that is remaining from the house when it was built originally.  Just look at that knob and think about how many hands have been laid on it.  Very pretty door plate, too, with that huge keyhole.
