A slightly inept wizard casts his spells which are demonstrated to us through the techniques of optical art.

In 1975, more than a decade into a career that would establish him as one of the most innovative children's book authors of his time, artist and illustrator Ed Emberley followed the gothic woodcuts of his previous book, Suppose You Met a Witch, with a complete left turn: the story of a prince turned into a frog, and the bumbling wizard whose spells take the form of dizzying optical illusions. Combining the bold graphic experimentation of the 1970s Op-Art movement with the charmingly irreverent storytelling for which Emberley is renowned, Wizard of Op is a visual odyssey like no other. Anthology is proud to reintroduce this little-known masterpiece from a wizard of children's literature.

One of the most beloved film musicals of all time, The Wizard of Oz represents an enduring family favorite and cultural classic. Yet there is much more to the story than meets the eye, and the MGM movie is just one of many ways in which it has been represented. In this lively and wide-ranging book, editors Danielle Birkett and Dominic McHugh bring together insights from eleven experts into the varied musical forms this great American myth has taken in the past century. Starting with the early adaptations of L. Frank Baum's story, the book also explores the writing, composition and reception of the MGM film, its importance in queer culture, stage adaptations of the movie, cult classic The Wiz, Stephen Schwartz's Broadway blockbuster Wicked, and the cultural afterlife of the iconic Arlen-Harburg songs. What emerges is a vivid overview of how music - on stage and screen - has been an essential part of the story's journey to become a centerpiece of American culture.
