The Siqueiros Image Bank is a collection of over 5000 images from the 20th century collected by Mexican muralist David Alfaro Siqueiros who compiled the photographs as source material and for the use of fellow artists as a means of inspiration and a source of found imagery. As Siqueiros wrote,

Nothing can give the [artist] of today the essential feeling of the modern era's dynamic and subversive elements more than the photographic document.
