I enjoyed this - a really nicely produced book - in an attractive format. The book has a wide range of artists some well known and others almost unknown. There are lots of examples of sketches by each of the 30 or so artists represented. As well as the wide range of techniques illustrated here - there is a commentary with each artist which gives a bit of a backstory to why they sketch. This makes for lot of material - and will ensure that I will want to dip into it again.
