A cigarette consisted of tobacco with a thin paper wrapped around it, intended to be inhaled, with or without a filter.
A vendor sold Camel brand cigarettes at the New York World's Fair in 1939. He tried to sell a box to Verne and Clara Brown, claiming that they were good for the inhalation area dubbed the "T-zone". He began stating Camel's slogan of "T for Taste, T for Throat. Camels will suit you to a T", before he was cut off by Emmett Brown.
