Item 21: Jorn Utzon Sydney Opera House photonegatives, ca. 1961-1965ca. 1961-1965This photograph gives some idea of the complexity of construction involved in the concrete shell superstructure of the Opera House. In 1963, instead of sending a traditional Christmas card to friends, architect Jorn Utzon created a box containing a cut-out photographic puzzle of the site, with the remark "It took several hundred men some years to put this together. I am sure you can do it in an hour."
