Here's a photo and info from John Knowles website of his award:

Chet caught me off guard when he awarded me the first honorary CGP degree at the 1996 Chet Atkins Appreciation Society Convention in Nashville
Here's a quote from Steve Wariner's website:
1997 - Received official “c.g.p.” status from Chet Atkins,who surprised him with a plaque and special recognition
And this:
c.g. p.
The abbreviation “c.g.p.” stands for “Certified Guitar Player,” a title that Chet
would bestow on a few guitar pickers that he knew. There were only four he officially
made c.g.p.’s: John Knowles, Jerry Reed, Tommy Emmanuel, and me. I am so honored
that Chet gave me that title!
I was thrilled when I learned I was nominated for a Grammy® in 1996 for my
work on No More Mister Nice Guy (which Chet played on). Then my elation went the
other way when I learned I would be up against my buddy Chet!
My wife and I went to New York to the show at Madison Square Garden, and
Chet won, of course. (He had left me a message on my answering machine saying, “I
voted for you to win; besides, I’ve already got 16 of ‘em,” then laughed.)
A week or so later, Chet called and insisted I come to one of his Monday shows
he was doing at Café Milano in downtown Nashville. I noticed a lot of cameras there that
night for some reason. He brought me up and not only “loaned” me one of his Grammy
Awards, but officially made me a c.g.p. with a beautiful plaque that I still have hanging in
my studio to this day! He was nothing but class.
I'm not sure if there is any video footage of John Knowles & Steve Wariner receiving their award or not. We need to at least find some info on Steve's award.
Also here's a link to Paul Yandell's offical C.G.P. presentation:
