See the magic behind the new 'Harry Potter' book covers

Johnny Duddle faced a huge challenge: Re-designing the Harry Potter book covers for a new generation of readers.

In an interview with The Telegraph, Duddle reveals how he was selected (the test cover that got him the job, pictured), his artistic process, and criticism received. “All I can really do, as an artist, is draw my vision of that scene,” Duddle told The Telegraph of the giant task at large.

What’s more, an accompanying slideshow shows the steps in how the covers were achieved for both Harry Potter and the Prisoner of Azkaban and Harry Potter and the Half-Blood Prince. Together, the images act something like a flipbook as color, highlights, and other details are added to the original sketches. The slideshow also shows early and completed sketches of Draco Malfoy, Severus Snape, and beloved house-elf, Dobby, among others.

Check it out, Potterheads, and as for Duddle, get this man a butterbeer!
