The Las Vegas and Tonopah Railroad Blueprints consists of twenty-four of the original thirty blueprints as part of the Interstate Commerce Commission (I.C.C.) Valuation Index Section I. They are labeled "Right-of-Way & Track Map, Las Vegas & Tonopah Railroad" and dated June 30, 1915. The blueprints contain four miles of railroad lines per sheet with a scale of 6 3/4 inches per mile. The collection also includes one sheet from the Bullfrog Goldfield Railroad company, which used the track, yard, and facilities of the Las Vegas and Tonopah and Railroad company between Beatty and Goldfield, Nevada.

The Las Vegas Ambassadors Collection (1968-1985) primarily consists of a scrapbook, newspaper articles, and photographs documenting the activities of the Las Vegas Ambassadors youth singing group. The materials were compiled by Harry LaFavor, the Ambassadors' business manager, who co-founded the group with Norman Kaye and Richie Astone to promote a positive image of Las Vegas. The collection also includes a songbook, vinyl record and ¼” tape recording, and promotional materials.
