Golden Gate International Exposition

1939 Treasure Island: Yugoslav Day at the 1939 World's Fair was sponsored by the United Yugoslav Societies of California. This was the largest gathering of Croatians ever to be held in the Western United States. The Slavonic Mutual and Benevolent Society was in the forefront of this expression of ethnic pride and contributed greatly to its organization and success. The United Yugoslav Societies Committee published a sixty page book on this occasion. The Queens of Yugoslav Day were Anka Vasilievich, Misses Katie Kordich, Dorothy Milosevich, Sophie Cosich, Elizabeth Talia, Winnie Eterovich and Helen Yugo.
