Reginald Marsh was an American painter, born in Paris, most notable for his depictions of life in New York City in the 1920s and 1930s. Crowded Coney Island beach scenes, popular entertainments such as vaudeville and burlesque, women, and jobless men on the Bowery are subjects that reappear throughout his work. He painted in egg tempera and in oils, and produced many watercolors, ink and ink wash drawings, and prints.

Tempera, also known as egg tempera, is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. Tempera also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint.
