A couple of months ago I attended the grand opening of a new exhibit at the Toronto Zoo called Tundra Trek. While I was there I noticed they were promoting it with a cool composite design made from symbols of local landmarks. I couldn't find it online at the time but just looked again and found it at adsoftheworld.com . Design by Lowe Roche, Canada.
Thanks to Joe Sapiano a long-time zoo volunteer (and my father-in-law) for the invitation to the event.
