This example was in with that bunch of pencils I recently bought from my friend Michael McNeil at Northwest Pen Works:
It is a Ritepoint, a St. Louis company that made some really neat and really fun pencils.
I've not seen one with this shape top, and when I first examined it, I was wondering what was up with that string on the top, until I turned it around and remembered a great line from Austin Powers: International Man of Mystery. "I can't remember the name . . .
but the fez is familiar."
I wonder if it came with a matching pencil holder in the shape of a tiny little car?
