These photos were taken during Pat O'Brien's travels to Europe, North America, and South America and thus are mostly made up of features of the cities that she found noteworthy, as well as sites of particular anthropological or archeological interest. The majority of the images were taken in Europe, especially Germany and Italy. There are also a significant number of photos of England and France. Some of these images were compiled into photo presentations, which are also represented in this series, along with the photographs.
The photos feature buildings (especially churches, historical structures, and museums), streets, statues, fountains, graves, pottery, art, artifacts, ruins, waterfronts, tourist locations, festivals, wide shots of cities, landscapes, and sites of anthropological, archeological, and geological interest.
