London's Victoria and Albert Museum is holding a curious exhibition titled "Disobedient Objects," opening July 25 and on view until Feb. 1, 2015. The show includes a variety of artistic tools that revolutionaries from a wide variety of cultures and time periods have used to help promote their social agendas, like protest signs, graffiti writing, and masks that hide the protestors' identities. Oppression is perhaps one of the best catalysts for innovation, and the exhibition "will demonstrate how political activism drives a wealth of design ingenuity and collective creativity that defy standard definitions of art and design," according to the press release. Here is preview of some of The Most Powerful Protest Objects used across history.
