A black and white photo of Katherine Johnson, taken at the same time as the photo in the first tweet. She is sitting at her desk, working on a computation spread out across one or two large sheets of paper. An analog adding machine and several books sit in front of her at the back of the desk, along with a translucent globe used in orbital calculations. Johnson appears to be focused on her calculation and is not looking at the photography.
