This sounds innocuous on the surface of things, but if you read this about doctoring of photos under Stalin – including signs in protests – it’s frightening: https://en.wikipedia.org/wiki/Censorship_of_images_in_the_Soviet_Union
“National Archives Apologizes for Alteration of Women’s March Image
Saturday, January 18, 2020
We made a mistake.
As the National Archives of the United States, we are and have always been completely committed to preserving our archival holdings, without alteration.
In an elevator lobby promotional display for our current exhibit on the 19th Amendment, we obscured some words on protest signs in a photo of the 2017 Women’s March. This photo is not an archival record held by the National Archives, but one we licensed to use as a promotional graphic. Nonetheless, we were wrong to alter the image.
We have removed the current display and will replace it as soon as possible with one that uses the unaltered image.
We apologize, and will immediately start a thorough review of our exhibit policies and procedures so that this does not happen again.
