Credits
Image credits.
The portraits of historical figures come from Wikimedia Commons. We only use images that are in the public domain or released under CC0, CC BY or CC BY-SA, and we credit every one of them here.
How we treat the images
Each portrait is cropped to a square, converted to grayscale and printed as a halftone in our poster colors. Those are changes to the original file. Where the original is licensed CC BY-SA, our halftone version is shared under the same license and version; where it is CC BY, the author credit below applies to our version too. Public domain and CC0 images carry no conditions, but we credit them anyway.
Figures without a freely licensed image show their initials instead. If you hold the rights to a better portrait, or see a credit that is wrong, write to corrections@politicaltests.org.
Country flags
Country flags are from flag-icons by Panayiotis Lipiridis and contributors, used under the MIT License. Historical states without an official flag in that set are shown without a flag.

We could not find a freely licensed image for these figures, so their pages show initials.
