The other reviews here pretty much say it all... if you are a fan of Calvin and Hobbes, you are going to love this! And, if you are already a fan, you will undoubtedly own a few worn-out copies of the various collections. I already have most, if not all of the books;
what makes this special and worth having (..in addition!) is the beautiful presentation, in chronological order, of all the strips, with the large cover art added throughout.
It is big, it is heavy, but bearing in mind that it will probably stay put and be well looked after, I don't see any problem with this! It's obviously not intended to be lugged about as your sole copy, and it's nice to have a nice hardback volume to sit and read. If you want portable, take one of your paperbacks. If you want your favourite (and the best, most imaginative, philosophical, entertaining cartoon strip ever) in 3 well-made volumes, then you should really add this to your bookshelf. I just did, having read the previous reviews, and I love it already!
(I've read Calvin and Hobbes through many times, and they just don't date either.. Calvin's comments about the advertising industry, and his Dad's views about t.v, the media, traffic etc are as funny and relevant today as when they were written.)
Not much more to say... if you love Calvin and Hobbes, this collection really is well worth it's weight.
