Should a student bring a pitch book to an interview?

What? No. Just do well within the confines of the interview. No need for game changers here.

Interviewee:

Hi, I've brought along this prop that I'd like to do a show-and-tell session on. It may have been prepared by my friend or someone else... you've got no way of telling. If it looks good, it's probably prepared by someone else. If it's a genuine effort by a student, then it will just be embarrassing for its ignorance. I know you have your own checklist of things you'd like to work through in this very time constrained superday interview, but can we burn up 5-10 minutes flicking through the pages of this instead?

Bringing in a pitchbook opens up the door for a line of questioning that you do not want to go down. As @"SSits" stated, if it is good, they will doubt it was made by a student. If it was made by the student, there will be formatting or content mistakes. The interviewer will instantly compare the work to pitchbooks made by the bank and that will not look favorable for the interviewee.
