Aquí os dejo el texto que viene detrás del libro "Quidditch Through the Ages. Kennilworthy Whisp" de J.K. Rowling:
If you have ever asked yourself where the Golden Snitch came from, how the Bludgers came into existence or why the Wigtown Wanderers have pictures of meat cleavers on their robes, you nee 'Quidditch Through the Ages'. This edition is a copy of the volume in Hogwarts School Library , where it is consulted by young Quidditch fans on an almost daily basis.
Proceeds from the sale of this book will go to Comic Relief, who will use your money to continue improving and changing lives - work that is even more important and astonishing than the three and a half second capture of the Golden Snitch by Roderick Plumpton in 1921.
