Bunnen was involved with the first photography class offered at the Atlanta College of Art in 1970. Less than six months later, she was invited by the then director of the High Museum of Art, Gudmund Vigtel, to be part of the exhibition "Georgia Artists Exhibit" the following year. In 1973, Bunnen and 13 others founded Nexus, the first photography gallery in Atlanta that showcased new work by emerging photographers, which now functions as the Atlanta Center for Contemporary Art. This iconic work from her early career captures a small figure framed poetically within a lone window piercing an unfinished exterior wall.
