You may have seen this bag (Done by designer Tim Pokrichuk) elsewhere already, I first saw it at the Russian design blog omami.ru, but its simplicity grabbed me.
For at least a week I saw everything around me in terms of its ISO size. So to get it out of my system I decided to do an A0 poster using the same concept. I quite like it so I took a pic to post. Not sure how long before the novelty wears off though.
