"It was a pictorial sheet, and Jo examined the work of art nearest her, idly wondering what fortuitous concatenation of circumstances needed the melodramatic illustration of an Indian in full war costume, tumbling over a precipice with a wolf at his throat, while two infuriated young gentlemen, with unnaturally small feet and big eyes, were stabbing each other close by, and a disheveled female was flying away in the background with her mouth wide open.

(Louisa May Alcott, "Little Women")
