Cant tell you how much I love these photos. The top three are by Bill Hicks, a man who was lucky enough to drive by Segre's- the Waterbury, Ct. fabricator of Calder's Stabiles- one day in the 60's to see this amazing sight, and thankfully for us had his camera! (courtesy The Mobile Factory- do read the entire post here ). And how great is the "Only Love Beats Milk" billboard?
Bottom photo likely taken the same year, from the book Calder's Universe, a must read.
