Also exceeding expectations was the auctions second session, featuring Property from the Estate of Mrs. Betty Jo BJ Graham of El Paso, Texas, a woman whose name might not hold celebrity status but whose remarkable life and many contributions to American history and the arts community of El Paso make her deserving of the limelight nonetheless. During the tumultuous times of World War II, Betty Jo Graham worked on the Cessna AT-17 training program, a crucial effort in preparing pilots for combat. Later, in 1956, she worked as an electrical wiring diagram analyst for Boeing Engineering Development on the iconic Enola Gay project.
A patron of the arts, Graham was also a collector of fine jewelry, with a particular fondness for eye-catching, statement-making pieces.
