The template and LOC website state that it applies to works part of a deed from w:The Economist Group, who owned w:CQ Roll Call from 1993 to 2018, with the collection itself having photographs from 1950s/1960s to early 2000s. The images listed are taken from after the deed, and I have doubts that the current owner would go under the same rights as it did when the Economist Group donated the materials, as they are now owned by w:FiscalNote (note the footer on Roll Call websites: "CQ Roll Call is a part of FiscalNote, the leading technology innovator at the intersection of global business and government. Copyright 2023 CQ Roll Call. All rights reserved”, as well as the “Copyrighted” status on some of the images’ metadata, e.g. File:Sal Rosselli.jpg). Permission section for many of the images state that the photographers are "recognized on the list of public domain CQ authors", but as I see it, they only apply to the work that is hosted in the collection, not for any future photographs taken by them.
