Where's My Cow?

Where's My Cow? is a picture book written by Terry Pratchett and illustrated by Melvyn Grant. It is based on a book that features in Pratchett's Discworld novel Thud!, in which Samuel Vimes reads it to his son. Where's My Cow? was released on 23 September 2005, to coincide with Thud!. The cover bears a gold sticker reading "OOK! The Ankh-Morpork Librarians' Award - Children's Winner". This looks slightly similar to the Carnegie Medal sticker on the paperback of The Amazing Maurice and his Educated Rodents. The book is a pop culture reference to the similarly named That's Not My series produced by Usborne books.
