This link includes some classic archival photos from the Shomria Institution, the first kibbutz education centre founded by the Hashomer Hatzair movement. It was located on Kibbutz Mishmar Haemek, overlooking the Yizreel Valley, which I had the good fortune to visit and tour last summer. It is a large, successful and still resolutely communal kibbutz with a storied history (several members have been members of Parliament), including as the site of a major battle during the War of 1948.
