Main Street USA: The lamps along Main Street are authentic 19th century gaslamps. In 1955, Disneyland designer Emile Kuri purchased the gaslamps by the pound from Baltimore, Maryland. More than 150 years old at the time, the antique lamps were being replaced and were meant to be sold off as scrap. (Additional lamps may have also been acquired from St. Louis, Missouri and Philadelphia, Pennsylvania.)
Note: Disneyland used to have a Cast Member dressed as a 19th century lamplighter, who actually lit the gaslamps at dusk.
