Artists' book described as: "The happening is the most delightful and exciting challenge to theatrical deadweight in many a year. Increasingly the young people put them on, while the theater institution wonders where everybody is and whatever became of Broadway. This book is the first book that attempts to deal in a concise way with all the aspects of the happening and its related forms and analogues. Al Hansen, one of America's leading pop artists and a pioneer in the development of the happening, here presents his delightful account of what this very lively medium is all about. No work of scholarship, the intent of this book is to inform, to provoke original thought on the part of the reader, and perhaps to suggest that he try his own experiments." -- from book's end-flaps.
