The signiture does not resemble any other MJ's that I've come across.
However he did make panda and cub paperweights, the most recent piece measures 4.5" by 4" and the earlier piece measured 6" by 6". Does your piece measure up to either of these. Can you show a picture of your whole piece to see if they match up?
