The same web site has this cool list of what they think is the coolest Ben Cooper costumes ever. Not sure I'd agree with the order, but many of those are my favorites(and I owned quite a few as a kid).
And finally is this article from last year about adult-sized Ben Cooper costumes. I've never heard of these, nor seen them so I'm curious if anybody else has. I'm going to go check into it. I'd love an adult Spidey, Mummy, and a couple of others.

Anyway, hope to post a couple more posts before this year's Halloween hits.
