For anyone interested in the current contemporary art market, this publication comes highly recommended. The book binding approach (or rather: lack thereof) is quite innovative, though the publication is definitely too large to easily take with you on public transport. It is ideally read at home on a desk. Each artist gets a minimum of two large A3 pages, some even get four. This leaves plenty of room for photos of up to 10 works per artist, and this will give you a much clearer insight into what a particular artist is all about.
A great overview of the current contemporary art world, and a great source of inspiration for curators, collectors, or artists.
