Icon is a good survey of Brandt's work. It's physically small but the reproductions are much better than in some of his bigger, more expensive books, far better than magazine reproductions.
Brandt's nudes-on-gravel-beaches got my attention in "arty" photo magazines forty years ago. I assumed I was seeing 28mm on 35...but it turns out I was seeing very wide angle 8X10 or larger.
I bought Icon as a catalog for a comprehensive traveling Brandt exhibit in 2008. Icon evokes the exhibit beautifully...the exhibit made Brandt one of my favorite photographers, with Avedon, Penn, Lyons, and Fusco...and that makes Icon important to me.
Brandt did a lot of physical (pencil, dye, bleach) retouching. You can see it easily in his original prints. That's important information...he wasn't uptight-Ansel-like. Most of his work had intense psychological or sociological or intentionally art-related implications. Icon depicts that as well as any, but no book could possively depict the nature of Brandt's prints, seen directly.
Icon is the least expensive Brandt... you do need it, even if you already own something more impressive for your coffee table.
