Punch was a British weekly magazine of humour and satire established in 1841 by Henry Mayhew and engraver Ebenezer Landells. Historically, it was most influential in the 1840s and 1850s, when it helped to coin the term “cartoon” in its modern sense as a humorous illustration.

In 1850 this illustration by Richard Doyle appeared in the May 11th issue #19 and was titled The Shadow of English Liberty in America. It showed a depiction of the allegorical statue of Liberty casting the shadow of a shackled slave (the visible obscuring reality).
