As a boy I had the "21st Century Foss" book. I don't recall how or where I got it, but I do recall the book quite vividly.
It was one of my favourite books - the sense of scale, the detail, the wonderful designs. Or, in some cases, non-designs - things built from scavenged parts, cobbled together yet somehow working.
That book, sadly, was not treated as well as it could have been. Filled with larger versions of book covers we thrilled to, I shared it with friends - it went to and from school in various bags, and it didn't really survive that well.
I've always wanted to replace that book. But luckily, this book is here now. And it's bigger, it's better printed, and well bound.
The book is well organised and fairly comprehensive, with all the famous works that you expect. It also has sketches from Foss' work on films, and plenty of text up front with details of his career and artistic development.
So it's a good book.
But if, like everyone else commenting here, you first saw Chris Foss' works on the cover of a novel and were electrified by them - immediately attracted and intrigued by them - then this is a great book.
This is the book you want.
And that is all you need to know.
