Hi Adam, :lol:
Long time no 'see.' I have the 2005 book and have just had a look. I agree that the shape in the book is a bit difficult to decipher as it is only sketch. The main difference is, towards the botton of the vase, the book shows that the sides should more be 'rounded,' whereas the vase shown in the link has decidedly squared off edges and it is not shown as dimpled in the book either. There are also fewer lines on the vase shown, than in the book.
However, I saw this and wanted to bid on it myself, as I think it is a good example, but the bidding has already gone way past my budget!
Now I can answer Frank's post in the cafe. Good pictures are essential!
