Slaughterhouse-five: what imagery do you remember the most from the book

I've been making a piece Of art on the last (always empty) page of the books I've been truly enjoying lately. I want to make one for my copy of slaughterhouse-five, but I haven't been able to think of a striking and legible enough image (no, I won't draw any tralfamadorians).

I know it's a weird question, but this is the place that made the most sense to ask. Thanks!
