I enjoy looking at good, creative design on business cards. They are so little and you don't have much space to put a lot of information, so I enjoy seeing creative resolutions. The first one I liked the color scheme as well as how simple and clean it is. The second I liked the humor of it. Every time you see this card you will know exactly who is for, so it send a very unforgettable message.
