Artifacts created or produced in former periods. The term was traditionally applied primarily to works of fine or decorative art and furnishings, but is currently employed for any type of man-made object of a past era. U.S. customs laws define antiques as artifacts whose date of initial purchase was at least 100 years before the present. In common usage with respect to automobiles, the term includes those at least 25 years old.
