This is promoted as the greatest art book of all time, and it may well be. Originally listed at $200, I bought mine on Amazon for $100 and thought it was a tremendous value. You can now buy it for $70. It is mammoth, which is the point, but you need to be careful to make sure you have the room for this masterpiece. At almost 1,000 pages and over 18 pounds, 13.9 x 2.9 x 18.7 inches, it is HUGE. But a once in a lifetime acquisition.
