"A tunafish sandwich on wheat toast, with lettuce and butter (no mayo), and a large glass of buttermilk." That was the start of the score for The Identical Lunch, one of Alison Knowles' most well known pieces of performance art. Adding in the option for a cup of soup, it goes on: "is eaten many days of each week at the same place and at about the same time." It has been enacted in various non-identical forms, all over the world, since its original inception in 1969. (As recently as 2012, MOMA hosted the artist for a series of "identical lunches" with visitors to the museum.) It is a uniquely enduring expression of the value inherent in thoughtful reflection of the everyday, the overlooked, and the routine. It is a story of how a tuna fish sandwich became a work of art.
