One of our visual design tasks was to design a portfolio and think about how to present work to potential clients. There's the obvious online portfolio, but I also thought that meeting people in person and having something to present without requiring a screen might be a good idea. So I did a mock-up for a small booklet, approximately A5-sized. I figure it could easily and cheaply be printed and handed out, and it's more informative than a business card.
Now, if I actually was to print something like this, I might dwell longer on which pieces I put in it, but this is abouts what sort of feel I'd like.
