Dick Brewer shaped and signed by Gary Linden...is it worth anything?

I have a nice 5'10 Brewer shaped and signed by Gary Linden. Definitely from the 80's.  Thruster with two glassed on fins and the center is removable with a free style fin. Does anyone have an idea what it is worth if anything? 

Lets just say you haven't struck Gold.  If it is in very good condition it would be worth something to someone.  

By the way Post a Photo! 

Yes please post a photo.

I probably worked on that board.
