During the month of June, CONTENTdm from OCLC has three Featured Collections of digital images in the spotlight: The Ohio Transportation Collection of the Columbus Public Library, the Strobridge Lithographing Company Circus & Theater Posters Collection of the Public Library of Cincinnati and Hamilton County, and the St. John Photograph Collection of Missouri State University. The digital images were made from the original glass plate negatives, owned by the Christian County Historical Society. The photographs probably were taken in the first decade of the 20th century by Mary (Garrison) St. John, a photographer from Ozark, Missouri. In 1909 she married James D. St. John, and the couple moved to Montana. Mary died in 1963.
