The North Las Vegas Bicentennial Committee Photographs and Drawings of Kiel Ranch document the buildings on Kiel (Kyle) Ranch in 1974. As part of the commemoration of the United States bicentennial, the North Las Vegas City Council elected to restore Kiel Ranch, which was one of the first non-indigenous settlements in the Las Vegas Valley. The materials include black-and-white photographs of Kiel Ranch as it was in 1974 as well as architectural drawings of planned renovations to the main house, the Brown House, the foreman's house, and the ranch hands' house.
