Ryan Lum is the founder and editor of Creative Guerrilla Marketing. He is passionate about creative marketing, social media and design.
Ryan has collected 122 examples of outdoor guerilla marketing that you can review by going to his site. Unfortunately it is very unlikely that you will be able to enjoy in Greece such examples, simply because the outdoor regulative framework, practically has limited outdoor to transport and bus stops.
So I will remind you first, just two special examples, that created joyful touches in our cities in the past (1983). We will miss such touches, till our politicians decide to re-examine if it is preferable to remain with the ruins of old poster sites, if it is preferable to continue depriving municipalities from the outdoor revenues they had in the past, or if there is merit in allowing outdoor, under a simple and easy to control framework, copying the best practices of modern cities around the world.
