Stop in New York City to see early 20th-century skyscrapers ornamented with an array of metallic ornament, from the Gothic tower of the Woolworth Building to the stainless-steel pinnacle of the Chrysler Building. Admire the gargantuan twin monoliths that are the World Trade Center, giant structures clad in metal and glass - sealed volumes made habitable by equally gargantuan heating, cooling and ventilating systems fabricated of sheet metal.
Leaving New York by the Staten Island Ferry, take in the Statue of Liberty, again a product of sheet-metal craftsmanship. Traveling west through New Jersey, Pennsylvania and Ohio, note warehouses, factories and farm buildings skinned in metal. All along the route are signs for shops and hotels and restaurants and every other sort of business made of sheet metal. In the Midwest, pass through one small town after another, each possessed of a main street replete with late 19th-century commercial blocks trimmed with sheet-metal cornices, window hoods and storefronts, a few with entire facades made of pressed metal. Enter any of these buildings and encounter tin ceilings and patterned metal wainscoting
