I've always been impressed with the high quality of the artwork in my D&D books - especially with the new generation of artists, like Wayne Reynolds and Todd Lockwood. The Art of Dragon Magazine holds to that standard.
A nice retrospective of 30 years of Dragon magazine cover and interior art, The Art of Dragon Magazine includes work from Larry Elmore, Clyde Caldwell, Brom, and many others, chronicling not only how D&D fantasy artwork has ebbed and flowed over the years, but how tastes and interpretations of classic characters have changed. Also, this book is chock-full of art. Neatly separated into broad categories (such as "magic" and "dragons") you'll find artistic interpretations of daring rogues, fiendish liches, gruff dwarves, and many other characters and settings that will fire your imagination. All of the art is well reproduced and clear - not blurry, and the book is put together well.
There are only two items that I feel keep this book from getting a five-star rating: first, it is too brief; while there is a large selection of art, one can't help but feel there are more gems out there (I hope a second collection is in the works!). Second, some of my favorite artists (most notably Todd Lockwood) are not as well-represented as I might have liked. Overall, however, fans of D&D, as well as fantasy art enthusiasts in general (including those who enjoy the annual Spectrum collections) will be pleased to add this to their libraries.
