A poster of the Irgun Zvai Leumi (National Military Organization), "Irgun" for short, which began its terrorist campaign against the Palestinians in September 1937, and was the parent body of the Stem Gang. The Hebrew letters inside the square stand for "the sole solution." This solution, as indicated by the map and the superimposed rifle, was the establishment of Israel by force on both banks of the Jordan River, i.e., in Palestine and Transjordan. The date of the poster is ca. 1946.
