Mineshaft is an independent international art magazine launched in 1999 by Everett Rand and Gioia Palmieri in Guilford, Vermont. Initially focusing on poetry and literature, the magazine began to publish comics after Robert Crumb became a contributor in 2000. The newsblog at The Guardian refers to Mineshaft's website as a source to find out more about Crumb's latest work.

Robert Dennis Crumb is an American cartoonist who often signs his work R. Crumb. His work displays a nostalgia for American folk culture of the late 19th and early 20th centuries, and satire of contemporary American culture.
