About This Project

direktTel 24


direktTel 24 offers its customers uncomplicated telephony. The best rates for internet access, cell phone and landline are selected and combined in a package deal for the customer.


It was envisioned to use the back of monthly invoices to present statistical facts about communication. These transform the invoice from ‘undesired’ mail into something interesting and entertaining: which country has the most cellular subscriptions per person? Who posts the most tweets? Which languages are most commonly spoken around the world?


The conceptual design was developed along with a logo, corporate stationery, verbal style and advertising concept.
