The Arthur Walker Gregory Photograph Collection, approximately 1900 to 1920, consists of black-and-white photographic prints, and two corresponding negatives. Two of the images depict the first train to arrive in Las Vegas, Nevada from Salt Lake City, Utah in 1905, one with railroad employees in the foreground. The remaining images depict Arthur Walker Gregory’s class photographs at the Las Vegas Grammar School when he was in the first, third, and fifth grades.
