To cite an artwork from an exhibition, follow the MLA format template. Provide the name of the artist as the author and the title of the work. List the exhibition’s name as the title of the container, followed by the exhibition’s opening and closing dates. Then specify the place where the exhibition was held, including the city, as the location:
