Harry Potter book covers (2007)

The publication of J K Rowling’s final Harry Potter book Harry Potter and the Deathly Hallows in 2007 was commemorated by a set of seven stamps featuring the colourful covers of all seven in the book series. In addition to the stamps, Royal Mail produced twenty labels alongside twenty Hogwarts house stamps, each one featuring a magic spell from the books, the secret of which was revealed when the label was warmed by hand.
