caption: The image shows a poster with two people standing in front of an atom, with the words "Adventures Inside the Atom: The Story of Nuclear Energy" written across the top. The two people appear to be looking up at the atom, as if they are about to embark on an exciting journey. The atom is depicted in the center of the poster, surrounded by a bright blue sky and a few stars. The poster has a vintage feel to it, with a muted color palette of blues, greens, and yellows.
