An Amazon reviewer complains because The Great Big Book of Tomorrow contains work published in previous collections.

Well, yes. There is a bunch of new stuff in there too, but as I’ve discussed many times on this site, it is a “greatest hits” collection, a career retrospective. So yeah, it’s true, I didn’t go back and draw a bunch of entirely new cartoons about the Bush I and Clinton years, nor do I have some vast stockpile of unpublished work that I’ve been keeping hidden away from everyone. Like every other oversized cartoon treasury ever published, from Peanuts to Doonesbury to Calvin & Hobbes, this book contains a substantial amount of work from previous smaller collections, and if that’s not what you want, you should not buy it.

But of course I hope you will.
