Risd Collaborative Portraits was a project organized by Susan Bickford, http://www.collaborativeportraitproject.com/. 175 Alumni from around the world, collaboratively made epic portraits of seven RISD faculty; Bob O'Neal, John Behringer, Ken Hunnibell, Marc Harrison, Mickey Ackerman, Seth Stem and Tage Frid. They were assembled at the RISD reunion in 2015.
