In this Article, work of art means an object, objects or surface embellishment produced with skill and taste. A work of art should generally be an original creation, rather than a mass-produced item, generally expressing, but not limited to, a social, cultural or historical theme. Works of art include, but are not limited to, paintings, sculptures, engravings, carvings, frescos, mobiles, murals, collages, mosaics, statues, bas-reliefs, tapestries, photographs, drawings, stained glass, fountains, or other decoration, either exterior or interior. The term does not include temporarily hung works of art, landscaping, or the choice or use of materials in architecture. (1984 L.M.C., ch. 1, § 1; 1995 L.M.C., ch. 12, § 1.)
