Just World Books has published a collection of political cartoons by Palestinian cartoonist Mohammad Sabaaneh:

Mohammad Sabaaneh, a talented political cartoonist from Palestine, has gained worldwide renown for his stark black-and-white sketches, which draw attention to brutalities of the Israeli occupation and celebrate the Palestinians’ popular resistance. These provocative drawings do not flinch from tackling the tough subjects that confront Palestinians, from Israel’s everyday injustices in the West Bank to their frequent military operations on Gaza. This collection includes 180 of Sabaaneh’s best cartoons, some of them depicting the experience of Palestinian political prisoners being held in Israel.
