This is a  4" round Christmas ornament decorated with sparkling silver glitter with images of a fairy and a mouse.  While it is an exact  image of Tinker Bell or Mickey, it certainly if a close reminder. It is  ornament from Harrods Department Store in London, England.
 
What makes it extra special is that It has been autographed by Margaret Kerry, Disney's reference model for Tinker Bell in the 1953 film, Peter Pan. She wrote "Tinker Bell" above her name and then signed her name and drew a heart underneath in silver felt-tip pen.
 
It is a great collectible for Tinker Bell and Disney fans!
