I've been searching the solution of my business card's style for a very long time. Frankly, it took me so much because somebody's business card is pretty much like a face, like a brand. So finally I've found mine. It is probably not the fanciest with all those crazy graphics but it says everything about me.
The concept is this clear: I pick up some sheet of paper (can be already used, so I recycle), I print my entire business card manually with a stamp, I cut it out and it goes like this every single time. The approach is very personal, very unique and very true. This is how I do my work and how I treat people.
