If you've read David Weatherly's ultra-creepy book, Black-Eyed Children (which is definitely a great read for Halloween!), you'll want the BEC t-shirt too, which is now available. (David's website linked here).
David sent me one and here it is.
And you can find an update on the BEC from David in my latest book, Men in Black. It's a paper that runs to 18 pages and which notes the deep similarities between the MIB and the BEC.
