In 1948 the new State of Israel was recovering from war, an influx of refugees from Europe, and was working hard to make sure every citizen was provided with what they needed on a day to day basis.
During this time, the State began encouraging immigration from English speaking countries like the United States, the United Kingdom and South Africa. In order to accomplish this they published a pamphlet.
They titled it, "Aliyah Olim" (Immigration Immigrants) and boasted that "in 1948 we had 125000, in 1949 we shall have 250000 Olim".
