A hardcover edition of Harry Potter and the Half-Blood Prince by J. K. Rowling, published by Bloomsbury. The volume is bound in publisher’s black cloth with gold-toned lettering to the spine, housed in a matching pictorial dust jacket. The dust jacket design, commonly referred to as the adult cover version, features a photographic illustration of a distressed copy of Libatius Borage’s Advanced Potion-Making resting on a wooden surface. The front panel includes the author’s name and title in gold-toned serif type, with the Bloomsbury publisher name printed vertically at the right edge. The interior pages are printed in a serif typeface on cream paper. The book appears to be an octavo (8vo) format typical of the Bloomsbury UK series.
