Lithography (from Greek λίθος - lithos, 'stone' + γράφειν - graphein, 'to write') is a method for printing using a stone (lithographic limestone) or a metal plate with a completely smooth surface. Invented in 1796 by Bavarian author Alois Senefelder as a cheap method of publishing theatrical works, lithography can be used to print text or artwork onto paper or other suitable material.

Lithography originally used an image drawn (etched) into a coating of wax or an oily substance applied to a plate of lithographic stone as the medium to transfer ink to a blank paper sheet, and so produce a printed page. In modern lithography, the image is made of a polymer coating applied to a flexible aluminum plate. To print an image lithographically, the flat surface of the stone plate is roughened slightly—etched—and divided into hydrophilic regions that accept a film of water, and thereby repel the greasy ink; and hydrophobic regions that repel water and accept ink because the surface tension is greater on the greasy image area, which remains dry. The image can be printed directly from the stone plate (the orientation of the image is reversed), or it can be offset, by transferring the image onto a flexible sheet (rubber) for printing and publication.

Charles Thomas "Chuck" Close (born July 5, 1940) is an American painter and photographer who achieved fame as a photorealist, through his massive-scale portraits. Though a catastrophic spinal artery collapse in 1988 left him severely paralyzed, he has continued to paint and produce work that remains sought after by museums and collectors.

Close was born in Monroe, Washington. His father died when he was eleven years old. Most of his early works are very large portraits based on photographs (Photorealism or Hyperrealism technique) of family and friends, often other artists. In an interview with Phong Bui in The Brooklyn Rail, Close describes an early encounter with a Jackson Pollock painting at the Seattle Art Museum: "I went to the Seattle Art Museum with my mother for the first time when I was 11. I saw this Jackson Pollock drip painting with aluminum paint, tar, gravel and all that stuff. I was absolutely outraged, disturbed. It was so far removed from what I thought art was. However, within 2 or 3 days, I was dripping paint all over my old paintings. In a way I’ve been chasing that experience ever since."
