Silkscreen printing is an old form of printing, but received a boost in the mid-twentieth century when advances in more quickly placing ink onto a canvas became possible. The artist who most enthusiastically adopted the method was Andy Warhol. Silkscreen printing allowed Warhol to quickly copy multiple images in different, usually bright, colors on one canvas. This very effect is captured by the dozens of images of Marilyn Monroe that Warhol printed in his Marilyn Diptych of 1962.

Cubism is typically involves an abstract representation of a subject into various geometric shapes, each from a different perspective.

Impasto is a painting technique in which thick layers of paint are used and create real texture and depth in the painting, often leaving visible brushstrokes.

Abstraction is a style of art that reduces shapes and appearances to basic yet recognizable forms. For example, a stick figure is an abstraction of a human being. The form of the human figure is greatly reduced to its most basic components, but it still recognizable. Generally you can think of it as the opposite of naturalism, a style that seeks to reproduce the forms of things as they appear in nature.  

Piet Mondrian was a Dutch artist who was the leading figure among a group of artists in different media who sought a style that was elemental in its construction, known as De Stijl, or "The Style." Mondrian's painting developed into featuring thick black lines intersecting the canvas at right angles to form rectangles on the painting. Inside these rectangles were blocks of color only in the three primary colors.

The twentieth century saw an explosion in artistic forms that both presented non-realistic images, especially Abstract Expressionism and Cubism, or depicted elements of everyday life or lower culture, as Pop Art did. In this, one of the key forerunners to these movements was the late-nineteenth-century movement known as Impressionism. Impressionism had vivid brushstrokes that made images look less realistic, and intentionally depicted scenes of everyday life, like farmwork, cafés, and parks.

The movement known as Pop Art was developed in the post-World-War-II era, taking inspiration from various elements of low culture and popular culture. Often, artists like Andy Warhol and Robert Raushenberg used advertising images in subversive ways, or as the actual artwork itself. Jasper Johns used images of Americana like the American flag in odd ways, while Roy Lichtenstein copied images from comic books.

Amedeo Modigliani was a Jewish painter born in Italy in 1884, but who gained fame in Paris in the 1910s. Embracing many aspects of modernism through associating with fellow modernists in the Montparnasse section of Paris, Modigliani established a unique form of portraiture which featured elongated shapes and empty black eyes. Modigliani died of tuberculosis at the age of 35 in Paris in 1920.

Abstract Expressionism was developed in the immediate post-World War II era as a specific genre of painting that featured non-realistic shapes and took inspiration from free-form styles of music like jazz. Earlier artists like Wassily Kandinsky were pulled into the movement, which was further pushed by artists like Jackson Pollack, with his "drip method," and Willem de Kooning, whose odd figures and textural paintings were archetypical of the movement.

Futurism arose from the destruction of World War I and the advances of the machine age as an artistic movement that championed modernism, speed, and technology. Its principles were set forth in the Futurist Manifesto, written by the Italian artist Filippo Tommasso Marinetti. The movement was primarily Italian, with a few prominent Russian adherents, and had an unfortunate close relationship with the Fascist movement in Italy under Benito Mussolini.
