Dr. Udvardy's and colleague Linda Giles' research revealed that two museums in the United States each held one of Kenyan man, Kalume's two stolen vigango (wooden memorial statues) in their collections. After the National Museums of Kenya wrote to each museum requesting their immediate return, which museum initially, and for quite some time, refused? The Denver Museum of Nature and Science. The museum at California State University at Northridge. The museum at Hampton University in Virginia, a historically black college (HBCU). The Illinois State University museum.
