Map of the cracks in the Guggenheim's facade. "Since the Guggenheim Museum opened in 1959, Frank Lloyd Wright's massive spiral facade has been showing signs of cracking, mainly from seasonal temperature fluctuations that cause the concrete walls, built without expansion joints, to contract and expand."
Regarding the doublestrike on the Guggenheim, Design Observer has a little more information about it. "I don't think [Frank Lloyd Wright] ever floated text."
They're refurbishing the outside of the Guggenheim and stripping away the facade reveals a doublestrike on the "T" in "The". It's like they started putting the printing on the building and then the architect stops by and says, whoa! that text is supposed to be lower, you morons.
