The listing, Professor Plumb Mover game piece from Clue board game has ended.
This is a mover gamepiece from a Boardgame named Clue.
It represents a character named Professor Plumb.
If I were to guess what it is made of, I'd say hard rubber.
I looked at it with a magnifying glass, and I Can't see a single sign of wear.
It's about twice as tall as a nickel is wide.
I will send this out as soon as possible after the end of the auction.
