A color photo of President Barack Obama presented Esther Conwell with the National Medal of Science in 2009. They are both wearing dark suits. Obama's back is to the camera. He is shaking Conwell's right hand with both his hands, and smiling at her. She is wearing glasses, smiling, and looking at the President. The medal, with a red, white, and blue ribbon, has already been placed around her neck. The ceremony took place in the White House; part of a gilt picture frame and the characteristic interior moulding of the WH is visible in the background.
