Oliver E. Aultman opened the Aultman Studio in Trinidad, Colorado in 1890. Using glass plate negatives and later, film, Mr. Aultman made studio portraits of thousands of southern Colorado residents. The portrait collection reflects the ethnic diversity of southern Colorado.  Aultman also photographed Trinidad and surrounding areas. Following O.E. Aultman's death in 1954, his son Glen Aultman operated the studio until his death in November 2000.  The Colorado Historical Society purchased Aultman Studio negatives from Glen Aultman during the 1960s. Glen Aultman later donated additional materials including  photographs, studio equipment, and furniture.

The collection includes approximately 50,000 negatives, as well as studio registers listing names, negative number and year. Study prints are available for some of the Aultman images. The study prints are arranged by subject (Children, Men, Women, Occupations, Trinidad Scenes) and by decade (1890, 1900, etc.). The study prints are not identified by name of the individual in the photograph. Some Aultman images may be viewed online.
