Who needs chirashis?
I collect them, but only as they are given to me as freebies over time. Throughout the past 8 years, though, I've accumulated about 300 or so of them.
What I like most about them is that they give you a very broad overview of the japanese posters that are out there. So, if you find art on a chirashi that really gets you, then you can look for the b2 or the b1. The only time I have not seen it translate like that is for the Pi chirashi, of which there are 3 or so. I've only seen one b2 version, and never a B1. Boy, if a B1 of one of those Pi posters ever came up, I would be unstoppable until I acquired it.
