"C.H. Duell" by Bain News Service — https://commons.wikimedia.org/wiki/File:C.H._Duell_LCCN2014686661.jpg — Public domain (news-agency photograph by the Bain News Service, no named photographer; the negative is marked 3-2-15, read here as March 2, 1915 (Bain negatives are marked month-day-year; the library's date of 1900 is a catalogue placeholder). US: public domain on the ground that Bain distributed its photographs to newspapers when they were taken, which counts as publication, and this was before 1931. Risk: whether this negative was actually distributed in 1915 has not been checked; if it was never published, an anonymous unpublished US work of 1915 is protected until 120 years after creation (end of 2035). EU: anonymous work, 70 years from first making available (or, if never made available, from creation), long expired.
