Since the 1960s the embellished bamboo chillum has become an American folk art form. These pipes are handmade and often sold by artists on street corners in places like the Haight-Ashbury district of San Francisco and the Greenwich Village area of New York City. The designs on these contemporary smoking pipes recall traditional decorated bamboo pipes from Borneo, however, the American carved bamboo design often employs a brass lighting fixture for a bowl. Since the 1970s, street artist Darrel "Pipeman" Mortimer of San Francisco has made nearly 10,000 such pipes, each signed, numbered, and sold personally.
