spring up like wildflowers after a summer rain... although the related sales websites claim it's been in business since 1999,

this is one offering that I spotted and wondered if anyone has any experience with them or knowledge of a track record?

They claim the following on their website;  http://justtheproof.com/

Unless otherwise noted, each autographed memorabilia item sold by Just Minors™ (with the exception of cards) comes with Just the Proof™ Authenticity. Just the Proof™ Authenticity certifies that the item was signed in the presence of and witnessed by a JMI representative. Information including the date and location of the signing is included along with a unique product identification code. Photography of the player signing the item is also printed on the certificate of authenticity. To complete the authenticity, both the item and the certificate are protected with holographic technology.  There is no better authenticity in the industry!

and then have a related sales web site and authentication claim; http://www.shopjustminors.com/home.php

Just Minors™ is the leader in producing cards and autographed memorabilia of top baseball prospects. Since its inception in 1999, Just Minors™ has continually delivered top quality, yet affordable products, as well as cutting-edge concepts. Just Minors™ was the first to offer packaged memorabilia products with its Just Stuff™ brand in 2000, which later became the very popular Mystery™ brand. Mystery Bats™ and Mystery Balls™ have become marker leaders in those categories. And, later in 2008, Just Minors™ will debut Mystery Jerseys 2008™, the first autographed/game-used jersey product of its kind.
