This guitar was custom made for Scott Ian of Anthrax when he was on The Simpsons. The front and back features every major and minor character on the show as well as an image of Scott. There were only two made and it took over 60 hours of work to complete.
You can see the likeness of Scott in the upper right hand corner of this photo of the guitar. He is on a Blue background if you need more help finding him, though he appears to be lacking his trademark beard thing.
Here is Scott holding the guitar!
