Although this isn’t really guerrilla marketing, it is a very interesting concept. In a way, it is street art, yet not done on the street. It’s Envelope art! Perhaps it’s the idea of custom envelope art that is ver intriguing as a marketing concept. Although difficult for mass mailing, perhaps just one doodle would make your mail marketing campaign stand out from the rest! Which one is your favorite?
