The United States was the most popular destination for Jewish immigrants between 1881 and 1924. After World War l the anti-immigrant movement overcame the United States, with strong restrictions on immigration to the United States. The exhibit includes a collection of Yiddish cartoons from the 1920s that protest US Immigration quotas that restricted Jewish immigration.
