Great file copies from the Industrial Designer who not only worked with JBL but was the lead Industrial Designer for Harman Kardon.
These first two pieces are held in the original JBL two section folder. A like new “Insight: JBL, an introduction to James B. Lansing, the Man, the Company, the Product” book that was intended “..to familiarize the reader with the fundamentals of loudspeaker design and production” and “..to judge for yourself the differences between good and bad loudspeakers and, more importantly, between good and great loudspeakers.”
Opposite this in the folder is “The Sum of the Parts” booklet and it is a detailed look at the construction of their loudspeakers and notes “The Whole is Equal to the Sum of the Parts”. This is also like new.
Finally you get a long multi folded brochure the the Contemporary line of speakers. This is meant to be folded twice but appears to have been scored but never fully folded fully as it is still tight at those folds.
