Group portrait of teenage girls beloning to a social group known as the 21 Club.

In 1921, twenty-one teenage girls, all Hebrew students established an apolitical friendship society and named it Club 21. Their younger sisters decided to establish a similar club, simply named Our Circle. Many of these young women emigrated or moved to larger towns during the 1930s.

Among the Club 21 members: Mattle Sonenson (front right) and her best friend Geneshe Kaganowicz; Zipporah Katz (third row, second from right); Leah Koppelman (top row, fourth from right).
