Switzerland. Zürich. An old man dressed with a black suit, wearing a watch on the left wrist and glasses, holds with both hands a tree trunk. He stands on the Bahnhofstrasse which is the main banking and shopping street. He watches the Sechseläuten parade, which celebrates the end of the winter. The Sechseläuten is a traditional spring holiday celebrated in its current form, usually on the 3rd Monday of April. © 1991 Didier Ruef
