Where's Waldo?, published outside the United States and Canada as Where's Wally?, is a series of children's books created by British illustrator Martin Handford. The books consist of a series of detailed double-page spread illustrations depicting dozens or more people doing a variety of amusing things at a given location. Readers are challenged to find a character named Waldo hidden in the group. Waldo's distinctive red-and-white striped shirt, bobble hat, and glasses make him slightly easier to recognize, but many illustrations contain "red herrings" involving deceptive use of red-and-white striped objects. Later entries in the long-running book series added other targets for readers to find in each illustration, such as a female counterpart of Waldo named Wenda, a dog counterpart named Woof (who's tail can only be found in the scenarios), a wizard named Wizard Whitebeard, and Odlaw, Waldo's doppelganger.
The first book in the series, titled Where's Waldo?, was published in 1987. The books became extremely popular and were localised for many different territories, with name changes for Waldo in certain regions. The franchise also spawned other media in a more storyline-based form, including a TV series, a comic strip and a series of video games.
