The Great Lakes Zephyr - Wind Energy & Hydrogen Journal

Back to Kettler Ecological Design - there is a very brief background on their renewable energy posters, which were designed and published in 1984. Also pricing and purchase information. I also found out that Alan Kettler is an alumnus of the University of Michigan in Geology. That makes it an official Great Lakes story. You can find out more about the posters at his page: http://www.kettler.com/posters.html There are four posters covering solar, wind, hydro, and geothermal. If possible, we may have more on Alan Kettler's story in the future. These posters would look wonderful in any collection, and they remind me of the style used in the Southshore Line rail posters. Almost art deco, almost. Beautiful work here.
