See, that is his house... and up top is his room. Down at the bottom is his dog, but that's not labeled.
And, at the bottom right is Dennis' disembodied head.
I like this one. It shows us so much about the "The Menace" family. They have a centrally located fireplace and they run it when leaves are on the trees, so they either live in a cold climate or Mr. The Menace has some nefarious documents that he must burn.
We also learn that they have some absurdly large amount of windows. No wonder Dennis carries a slingshot.
