polaroidpandawolf asked: I was a little disappointed when I went to see the Mark Wallinger exhibit recently. Not only are there two bricks numbered 27 (something quite a few people have noticed). We also discovered that while the handwriting of the numbers appears to be the same it was done by a team of workers using a sample of Wallinger's handwriting. Sure it's a big task to expect him to do them all himself but he only did about 100 of them. Still it is neatly organised.
