Polish modern art was collected by leading figures within America's cultural vanguard. Most prized the art's stylistic innovation; they were likely unaware of the ideological charge that animated modernism's makers. By the end of the 1930s, numerous exhibitions of Polish art had been mounted in the United States; however, few concentrated on strikingly innovative works, preferring instead traditional themes, genres, and styles. Nonetheless, Poland's modernist efforts garnered popular success at the New York World's Fair of 1939. The modern art from other central and eastern European nations was actively promoted by its makers, who had immigrated to the United States. Poland's modern art did not benefit from a similar presence, its modernists having mostly elected to remain in their native land. The paucity of Polish artists in 1930s America compromised their chance to exercise an influential role just as the United States was consolidating an international canon of modern art.
