[4E] Chapter art in DMG -- Old adventures?

[direkobold]

So I just got back from a midnight release party and I'm thumbing through the DMG, and I realize that the art at the beginning of Chapter 2 is the final room from S4 - The Lost Caverns of Tsojcanth and then the open art from chapter 4 is the final room from The Forge of Fury.

I'm still working my way through, but my question is. Is all the chapter art from adventures, and I'm just not recognizing it. If it's not everything is it still more than those two? If so what other adventures are featured?

I quickly paged through the PH but none of the art clicked as being from an adventure, but it is way past my bedtime so I'm not firing on all cylinders.

Chapter one could be from Keep on the Borderlands.

Chapter eight was the last thing my PC saw in at least three or four campaigns.
