When trying to determine if a table lamp is vintage, look for certain characteristics that are common in older pieces. Generally speaking, vintage lamps will have more intricate design details than modern lamps and may feature detailed carvings or hand-painted artwork on the base. Additionally, they often use heavier materials such as brass or cast iron and can have unique features like pull chains or heat vents. Look closely at the wiring to see if it's been updated recently; most vintage lamps use cloth covered twisted cord which was commonly used before 1950s. Finally, examine any stickers or markings on the base of the lamp; these can provide clues about when and where it was made.
