Jackson Guitar, custom made to promote the movie "Rock of Ages"
which featured among others Mary J. Blige & Russell Brand.
Also signed by dancers Diego Boneta (bottom left), Julianne Hough (top left).
Director Adam Shankman signed on the top far right.

It is based on the Jackson Solist model and there are only 37 of these guitars made by Jackson.

I bought this guitar from someone that had won a contest on
dutch radio but had no interest in the item. 
I also have a signed poster from this movie and a COA for the guitar and the poster.
