The University of Oklahoma has taken over the care and preservation of two of the state's top 10 endangered artifacts.
The list of endangered items was created by a committee of the Oklahoma Cultural Heritage Trust. The two items in the university's care are 1920s era organ player rolls and Spiro lace that was found buried beneath Craig Mound in eastern Oklahoma.
The lace was unearthed in the 1930s in an area known as one of the most significant ceremonial sites in the United States. The site was actively used from 800 to 1450 AD.
The organ player rolls weigh in at nearly 12 tons. They were made by the M.P. Moller Organ Company in the early 20th century.
