Collections: door knobs

Since this house has gone through many owners, many tenants, and many decades, it has ended up with an eclectic mix of fixtures and materials. These are small details that don't come through in other posts, so this is a chance for me to show you the "collections" in this house.

My house somehow ended up with quite a variety of plates and knobs. They're all different shades of metal, different levels of embellishment, and tend to rest at different angles. And who on earth paints over door handles?!

Yes, the gem on the left is from the back hall of shame.

Oval knob with round plate, round knob with oval plate.

I have no idea where the stripes came from.

And a bonus:

Yep, the door knob punches right through the plaster.

Do you prefer embellished or plain door knobs? Would you ever paint over one?
