NASA's unbelievably sadistic coloring book

It's the last day of the Apollo 11's Command Module tour's stay at Pittsburgh's Heinz History Center, and I enjoyed taking a look at the capsule that splashed down 50 years ago, returning NASA's moon-walkers to planet Earth.
What really caught my eye, though, was this coloring book in the NASA gift shop set up for the tour. What the hell, NASA?
