Query: Is the Hubble Telescope Included?

An unrivaled work, despite slight errors throughout. HOWEVER, it is unusable for playing (are you listening, publisher Hal Leonard?). I had the humiliating experience of being asked to leave a major photocopying chain for making enlarged copies - copyright infringement. Musicians, buy the book only if you want expensive filler for your bookshelf.
