Santa Claus is generally depicted as a portly, jolly, white-bearded man, often with spectacles, wearing a red coat with white fur collar and cuffs, white-fur-cuffed red trousers, red hat with white fur, and black leather belt and boots, carrying a bag full of gifts for children. He is commonly portrayed as laughing in a way that sounds like "ho ho ho". This image became popular in the United States and Canada in the 19th century due to the significant influence of the 1823 poem "A Visit from St. Nicholas." Caricaturist and political cartoonist Thomas Nast also played a role in the creation of Santa's image. This image has been maintained and reinforced through song, radio, television, children's books, films, and advertising.
