Associated Press images distributed to news organizations in the United States between 1929 and 1963 did not have their copyright renewed and are in the public domain. See more in the AP Commons Category here.

The Library of Congress writes: "In an attempt to determine if AP/Wide World registered any copyrights and if those copyrights were renewed, specialists in the Prints and Photographs Division of the Library of Congress searched the Copyright Office files. It was found that only a few images were registered for copyright and those copyrights were not renewed."

1. This work was published before 1964, and the copyright was not renewed. As such, the opportunity for copyright protection on the photo was forfeited and it entered the public domain.
2. The source images linked above are mechanical scans of the underlying public domain work. These scans are faithful reproductions of the photograph that do not meet the threshold of originality necessary to assert a copyright interest.
