In 1936AD all four sisters have been photoed together as following: Marica (behind), Beila (looker's left), Tila (looker's right), and Dina (forward). Meanwhile this photo got lost. In 1960AD, during the summer holiday, knowing nothing about the existance of the lost photo, the 4 (four) sons of the 4 sisters have been photoed together, unintentionally - each son in his mother's place. In the early 1960s, during Beila's and Tila's emmigrations to Israel, the 1936 photo has been found again.
