The Lagavale family, dressed in their Sunday best for the White Sunday holiday church services, cheerfully pose for the camera in Western Samoa. White Sunday (also called Children's Day) is celebrated on the second Sunday of October each year. In this tradition brought to the island by the London Missionary Society, the children receive new clothes and gifts, and festive games are played. The Lagavale family lives in a 720-square-foot tin-roofed open-air house with a detached cookhouse in Poutasi Village, Western Samoa. Material World Project.
