The United States Conference of Catholic Bishops Lantern Slide Collection consists of a series of 111 slides. The slides were all orinally housed together in the same box. They appear to have been created for use with a lecture or presentation detailing the National Catholic Welfare Conference's work with veterans of the First and Second World Wars in the United States. The slides dated ca. 1942-1946 are in black and white, the slides dated ca. 1927 are mostly in color. They feature photographs of social events, religious events, National Catholic Community Service and National Council of Catholic Men sponsored events, United States' Armed Forces personnel, children, and assorted National Catholic Welfare Conference organizational charts. Many of the slides prominently feature African American soldiers, children, and interracial events or groups. There are also slides of women in Armed Forces uniform and their work contributing to the war effort. Locations named in slides: Connecticut, Georgia, Illinois, Indiana, Iowa, Kentucky, Missouri, Nevada New Hampshire, New York, Utah, Virginia, Washington, and Washington, DC.

Slides 1-8, 10-14, 24-26, 44-46, 49, 51-56, 65-71, and 79 appear to have been created in 1927 to highlight the efforts of the National Catholic Welfare Conference during World War One.
