Damn thing has achieved cult-like status, I guess. Architects will soon be talking in terms of having to sell or being able to buy Zumthors, when they discuss the economy.... For a while I started flirting with the idea of buying more of these rare design books to make money because I was so familiar with their prices from always checking Amazon, but then out of nowhere they'll either pop up at lower prices or there will be new prints which made it too unpredictable to turn into a money maker. So I don't bother with it. I was trying to get this Diller and Scofidio book a couple years ago and it was going for $700-800. It was the book. Now it's under $200.
