The checkered box is an obvious fake.
I personally sold the Hen Tricks caller to the seller last year. It was sold to me at the Nats a few years ago by a very reputable collector and friend of Neil. The call was authenticatd by two close friends of Neil. The Hen Tricks call was not signed and was sold as such. I sold it on E-Bay for a fraction of what I paid for it in a "No Reserve" auction.
The sellers story about the history of the call is embellished significantly, but the call is what it is. A Hen Tricks caller with solid provenance and no signature.
