A San Francisco artist named Isabel Samaras created this.  It's called "Mocking Box: The Rap Wars".  I won't disclose the price but you'll need a few 7700s to purchase.  She has a blog here: http://isamaras.wordpress.com/

Her artwork, including this painting were recently included in an album by hip hop producer Madlib:

pretty interesting how we see more often  our precious boomboxes, in music videos and commercials and now even in art work, more people are trying to get a piece of the action.
even on ebay some one is selling  boombox oil paintings.
