Reddit reviews The Indispensable Calvin and Hobbes: A Calvin and Hobbes Treasury (Volume 11)

A gun.

More seriously, popcorn bags to microwave are easy to find. So are Kitkats (isn't it from Nestlé, a Swiss company?). Lays are very easy to find too. Here is a perfect list :

Beef jerky, definitely. And Reese's. And Fluff.

Oh.. and a big album of Calvin & Hobbes (written in English of course). Especially if there are children learning English (14-18 yo). But also without children, you can't be wrong with Calvin & Hobbes. I like this one.

If they're into board games, maybe a small game with cards written in English. Like Black Stories or Cards Against Humanity.

That's all I want. Can you bring me all these stuff? (not the gun).

The Authoritative, The Essenial and the Indispensable

Can be bought together, used, for well under $20, and that should cover most (or a very good portion of) the comics.

This was my first Calvin and Hobbes book. I think its a good one to get someone that has never read them into it.

My gift this year for my 7 year old nephew

Yep. With "Indispensable" and
"Exploring" you should have everything as far as I know. And no reason I can see to get paperback when you've got the hardcover.

The answer is always Calvin and Hobbes.

I've got 3 books going right now. I can't decide on what new book to read, so I'm rereading The Knight, Someone Comes to Town, Someone Leaves Town, and The Indispensable Calvin and Hobbes.
