The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.
Negative

Negative

Believe It or Not? Well, frankly, I don't believe all of it, though I'm sure those folks in West Virginia saw something mighty interesting. But in all the lengthy annals of Fortean/ supernormal/ paranoia-lit journalism, Keel does stand out as an author with an above-average storytelling ability. He also has the ability to not take himself entirely seriously, a trait often sorely lacking in the genre. With all that and a trans-phenomenon Grand Unified Theory of Weird Stuff to offer, this book is definitely worth checking out for those interested in the field.

Positive
