An "Ash Can" is a type of container designed to hold ashes and other waste materials, typically from fireplaces or cigarettes. These cans are often made of metal or heat-resistant materials to safely contain hot ashes and prevent fires. They usually have a lid to keep odors contained and to protect against wind or rain. In art, the term "Ash Can School" refers to a group of American painters in the early 20th century who focused on depicting everyday urban life. Artists like Robert Henri and George Luks aimed to capture the gritty reality of city scenes, often portraying working-class subjects and the vibrancy of city streets.
