Antonakos's artistic development can be traced chronologically in the exhibition files from some of his earliest work with neon in combination with found objects, to the use of neon alone. Exhibition files document the artist's progression from placing neon on a base or wall and at the corners and ceilings of rooms, to placing tubes at the edges of panels in order to generate a colored glow around them; furthermore, they document the evolution from his early boxes, contained spaces, and indoor and outdoor rooms, to his meditation spaces and chapels. Also in evidence in this series is the artist's prolific output of drawings, which were shown in numerous exhibitions. Exhibition files include documentation from circa 100 solo shows and from his over 250 group shows, at venues including Allentown Art Museum, the Benaki Museum, The Drawing Room, Galleriaforma, Genoa, Ileana Tounta Contemporary Art Center, Athens, John Weber Gallery, La Jolla Museum of Contemporary Art, Lori Bookstein Fine Art, the National Museum of Contemporary Art, Athens, Rose Art Museum, and the Savannah College of Art and Design. Many of the files include Antonakos's original drawings and plans.
