During the administrations of Presidents Wilson, Harding, Coolidge, and Hoover, the National Photo Company supplied photographs of current news events in Washington, D.C., as a daily service to its subscribers. It also prepared sets of pictures on popular subjects and undertook special photographic assignments for local businesses and government agencies. The bulk of the images were created between 1909 and 1932. The photographic files of the National Photo Company, including an estimated 80,000 images (photographic prints and corresponding glass negatives), were acquired by the Library from its proprietor Herbert E. French in 1947.

This collection is made of historic photographs of trucks that belong to the period before the end of World War I. Like every similar Picryl collection, this image set is made with aid of neural network image recognition. A manually picked dataset to train the machine was required first. Once trained, the AI made it possible to go through millions of images to find possible matches. Without this, extensive multi-sourced topical collections would be impossible to create. The image tagging process requires quality control to get rid of false-positive matches. Without human oversight, in this set, there would be false positive things on wheels such as carried artillery, horse carriages, and so on.
