A hugely sought after first edition of Harry Potter and the Philosopher's Stone will go on auction for £30,000 this week.
The edition of JK Rowling's very first book is one of just 500 ever printed, making it one of the rarest copies in the world.
Around 300 prints were sent to schools and children's libraries when published in 1997 – meaning just 200 are in the hands of the public.
