Sole edition. A "hero" prop which was used on set by the cast, notably by the character of Luna Xenophilius Lovegood on the train journey to Hogwarts. In the film adaptation of Harry Potter and the Half-Blood Prince Luna rescues Harry from Draco Malfoy's compartment on the Hogwarts' Express using her Spectrespecs, which allow her to see wrackspurts around Harry's head when he is hidden beneath his invisibility cloak. Spectrespecs were distributed free with this special copy of The Quibbler. According to Luna the glasses were designed to make wrackspurts, which are "invisible creatures that float into one's ears, causing them to go fuzzy", visible to the wizarding eye.
