Jørn Utzon is 90 years old this year and the Danish Architectural Press’s Architectural Magazine dk asked some Architects to send him a sketch greeting and they obliged. The result is dk 2008 02 a fantastic issue given over mostly to sketchs of Utzon’s some never seen before, and to sketches and letters to the Architect by other leading Architects, the issue I guess will be hard to get hold of for most people but arcspace has a small excert of some of them that is wonderful to look at. Someone has also put up a gallery of his work on flickr (via). So Jørn Utzon happy birthday and thank you.
