Che Guevara by Jim Fitzpatrick (1968).

An iconic image, this print is from Jim Fitzpatrick's original silk screening of Alberto Korda's photograph of Argentinian revolutionary Che Guevara. A proud Dubliner, Fitzpatrick created the image on Guevara's death. "When he was murdered," explains Fitzpatrick, "I wanted to do something about it, so I created the poster. This image had to come out, or he would not be commemorated otherwise, he would go where heroes go, which is usually into anonymity." Fitzpatrick produced the image without copyright, only obtaining a copyright in 2010, and has since granted the rights in perpetuity to the Guevara family.
