<p>These whimsical collections of photos appeal to the voyeur in all of us. Each book is inspired by a single, deceptively simple concept-bags in trees, looking upward, items that say "thank you"-and the resulting photo essays are surprisingly illuminating. BENEFITS OF LOOKING UP contemplates the surprising and uplifting moment of finding a balloon trapped in a tree.</p><p> These are an outgrowth of Partners &amp; Spade's ongoing publishing program of concept photo books. They have already created dozens of titles with limited print runs, sold only in their gallery and select stores. We have chosen the best and most inspiring of these studies to bring to a larger audience.</p>
