...I saw at San Diego Comic Con from artists who came for portfolio reviews.
First was an artist who printed an actual blank blueline comic page on the back of his business card. Before he gave it to you, he asked you who your favorite comic character was and then did a quick little sketch of that character on the back of his card. Yes, it was a little time-consuming, but it sure as hell made an impression on me.
The second was the portfolio of a kid whose samples were about an artist coming to San Diego to show editors his portfolio. It was cute and well done and got editors talking.
Both pretty original ideas and left their mark on all who saw them. Nice job, guys!
