Two rare pieces of original artwork from the front covers of J.K. Rowling's best-selling Harry Potter series have emerged for sale for a whopping 20,000 pounds.
The watercolour sketches depict famous scenes from The Chamber of Secrets and The Prisoner of Azkaban, the second and third of the groundbreaking Harry Potter books.
British artist Cliff Wright designed the the cover art for The Chamber of Secrets which features trainee wizard Harry, pal Ron Weasley and his owl Hedwig flying in a magic Ford Anglia car.
Harry and Ron steal the fantastical car from Mr Weasley so they can travel back to Hogwarts School of Witchcraft and Wizardry in the 1998 follow up to The Philosopher's Stone.
The following year Wright was commissioned to illustrate the third book in the series The Prisoner of Azkaban.
For the front cover, he came up with an image of Harry, played by Daniel Radcliffe in the film franchise, and friend Hermione, portrayed on screen by Emma Watson, travelling back in time.
The pair are shown riding on the back of Buckbeak, a mystical hippogriff - part eagle, part horse.
The illustration up for sale is Wright's third draft and features handwritten notes in the margins.
The Chamber of Secrets cover art is expected to sell for upwards of 12,000 pounds when it goes under the hammer, while bidding for the Prisoner of Azkaban illustration starts at 7,500 pounds.
They are being sold by Los Angeles auction house Nate D. Sanders on behalf of private owners.
