File:Col. De Orbeta - Ponce Massacre (El Mundo).jpg
In accordance with the "Copyright Term and the Public Domain in the United States (January 1, 2009),[1] images published with notice but with no subsequent copyright renewal from 1923 through 1963, are public domain due to copyright expiration."
El Mundo, which went out of service in 1986, could not have renewed its copyright which expired. Therefore, since Puerto Rico fell under US copyright in 1937 as well as today, this would make the Ponce Massacre image public domain. (UTC)
