Awesome Graphic Design: Those cards are usually printed on paper with some special effect like filmed or polished. The words on it can be cut in relief or intaglio. And you will also find some really creative combination of color and texture.
The card draws you in based on the fun design, and while there is no type on the outer cover, I'm not sure it matters because it establishes branding and creates interest to see what is inside. The wine bottle cutout is clever, so as the business card is pulled out it makes the bottle seem empty.
