If you're looking to add attribution, these are the sources I've found: - Main source/credit: JPL/NASA, via https://www.jpl.nasa.gov/images/the-grand-tour-jpl-travel-poster (where JPL is the agency that was commissioned by NASA to create the poster series) - Illustration: https://www.invisiblecreature.com/, according to https://www.posterpresentations.com/nasa-posters-the-grand-tour.html

Thanks that is perfect. Much appreciated.
