Credits

Every photograph on the Inside the Machine cards is reused under a public domain release or a Creative Commons attribution licence, read from the Wikimedia Commons record on 21 October 2026. No photograph under a share-alike, non-commercial or no-derivatives licence is used on a card. Each was cropped to the card window and converted for print; nothing was retouched, combined or generated. Each card carries its own short credit, and the two credits cards printed with the set carry the file page and licence for every one. This page is the same information for the web.
