Hello Kitty Apparently Very Comfortable With Park Avenue Address

Ok, so I am really late to this one! This exhibition by Tom Sachs, the "Hello Kitty Wind-Up" has been in place since May of last year. But, I ask you, has Hello Kitty refused to vacate? I've done numerous searches on the net , and they all seem to imply that the Hello Kitty exhibition was to run until September 6th, 2008.

So, is she, Miffy, and her friends squatters? Has the Lever House taken them to housing court yet? Have they been served? I guess Hello Kitty is very comfortable just where she is and why not, it's Park Avenue afterall!
Regardless of her status, passerbys still seem to get a big kick out of the 21' painted bronze.
