This is a page from The Bug Book by Edward Gorey. The story is about a bunch of bug cousins who are happy and carefree until this new bug (the one in the illustration above) arrives, breaks up their parties, and waylays them whenever they go visiting. The cousins conspire to solve the problem by rolling a rock off a cliff to crush the big bad bug, which they successfully do. The story ends with them slipping the remains into an envelope, addressing it “To whom it may concern”, and propping it up against the fatal stone. That’s it. Then they throw a party.
Edward Gorey, if you’re somehow in charge of the universe in your postmortem form, I just know you’re the scriptwriter for 2020 and those bugs finally mailed that envelope.
