The Joyner/Giuffrida Collection of Abstract Art is widely recognized as one of the most significant collections of modern and contemporary work by artists of the African diaspora and from the continent of Africa itself. Four Generations: The Joyner/Giuffrida Collection of Abstract Art draws upon the collection's unparalleled holdings to explore the critical contributions made by Black artists to the evolution of visual art in the 20th and 21st centuries. This revised and expanded edition updates Four Generations with several new texts and nearly 100 images of works that have been added to the collection since the initial publication of this influential and widely praised book. Lavishly illustrated and featuring important contributions by leading art historians, critics, and curators, Four Generations gives an essential overview of some of the most notable Black artists and movements of the past century, and their approaches to abstraction in its various forms. Filled with countless insights and visual treasures, Four Generations is a journey through the momentous legacy of postwar art of the African diaspora.
