The Rainbow Swash is the common name for an untitled[1] work by Corita Kent in the Dorchester neighborhood of Boston, Massachusetts. The rainbow design painted on a 140-foot (43 m) tall LNG storage tank was copyrighted in 1972,[2] and was claimed to be the largest copyrighted work of art at the time.[3] Highly visible from daily commuters' drives on Interstate 93, it is considered one of the major landmarks of Boston, akin to the Citgo sign.[4][5]
