The Protest Types began as personal project by designer Octavio Pardo to reflect on the shapes and voices of protest signs. So far it spans four font families, each with a different voice.
Protest Guerrilla is an stencil version of Strike - a solid but peaceful font.
An import and novel design feature of the project as a whole: Strike, Guerrilla and Riot all share the same spacing and kerning. This means designers have the possibility to write a message, and then decide the level of passion (or anger) that they want to express that message with, without altering any line lengths or page layouts.
