You have to give this book five stars, because there isn't any competition (nor likely to be); but it's not without its limitations; too much crammed into too small a space. The majority of decent portraits are BIG, and the vast majority of these illustrations are tiny. If you're looking at art in a book you want the illustrations to be as big as possible - and this is a small format book to start with, only around 10"x8", and if I tell you that you may find a 6ft, a 3t and a 2ft picture stuffed onto a single page, and still with plenty of empty white space, too, you will see what I mean. The suffers are the photo-realists - their works - which are often big - look more like photographs than photographs. As for examining brushwork - forget it. So in effect, it's a book of thumbnails. Nevertheless, it IS a 21-year history of this prestigious art competition, and if you're interested in that, this is the (only) book for you.
Large compendiums of portraits make for depressing viewing; sitters cannot sit with a fixed grin for hours on end (and if you see a smiling portrait, it's 9999 to 1 it's been painted from a photograph; which is OK) so the overall effect is one of dourness, even depression. It doesn't end there, though; some of the portraits are either hideous or repellent or, you would have to say, totally pointless or, even, not portraits. These categories tend to feature most in the nineties; towards the end of the 21-year period, whilst the dourness remains, the hideousness, repulsion and pointlessness diminishes (although not diappearing entirely by any means)- reflecting, one supposes, the changing of the guard on the judges' bench... And a jolly good thing, too. Perhaps in the next 20 years, we can swing the pendulum even more towards beauty, confidence, inspiration and hope, before it starts swinging back to ugliness, poverty, sickness, misery and death. Art is for decorating walls; I wouldn't want a deathbed portrait on my wall (unless it was by Hogarth or suchlike).
