Biden's windows are adorned with the flag of the United States and one with the presidential seal. (Trump previously included flags representing each branch of the military.) Biden also added a portrait of Benjamin Franklin, completed by Joseph Siffred Duplessis in 1785. The painting is reportedly meant to symbolize Biden's trust in science. In the bookshelf beside the painting, a moon rock on loan from NASA is displayed to represent American ambition and ingenuity.
