I've long been a fan of business cards that are so unique that they become, essentially, impractical. The blogosphere is rife with interesting business cards, but this is the first time I've seen concrete business cards. Impractical? Maybe. But the awesomeness of these makes them total worth it.
French creative agency Murmure created these concrete cards as a way of playing with the notion of scales. The ubiquitous material, used in large scale creations primarily, was enhanced by using the "smallest and most refined communication support".
