An extraordinary UK Bloomsbury first edition, later printing of Harry Potter and the Prisoner of Azkaban that, due to a number of very unusual printing and binding errors, should never have entered the public domain. Firstly, the printing of the cover illustration is shifted by 0.9 cm, causing the bottom edge with the quote "Winner of the 1999 Whitbread Children's Book of the Year" to be missing. Due to this shift, a white and cream-colored border with blue offset print marks is visible at the top. Even more strikingly, the wrongly printed cover is bound inside out, resulting in the outside of the book being entirely blank. As if there weren't enough production errors, the copyright page is also speckled. Besides the mentioned flaws the book is in a fine unread condition. Most likely a completely unique specimen and therefore a very special collector's item.
