Artists Leonardo Drew and Jennie C. Jones with Pamela J. Joyner, collector. The Joyner/Giuffrida Collection of Abstract Art is widely recognized as one of the most significant collections of modern and contemporary work by African and African Diasporan artists. Four Generations: The Joyner Giuffrida Collection of Abstract Art draws upon the collection’s unparalleled holdings to explore the critical contributions made by artists to the evolution of visual art in the 20th and 21st centuries.
