Additional Signature on Signed and Numbered Comic 0

[SNORRIS]

Newbie autograph question...If I purchase an already signed comic from the publisher (in this case the new "John Wick" signed by author Greg Pak), would it be in my best interest to attempt to have the comic signed by the artist (Giovanni Valletta) and witnessed by a CGC rep prior to CGC submission?  I've got no idea if the Greg Pak signature comic is part of a "limited edition" or if there's any sort of authentication from publisher Dynamite.

Also, since I'm on the John Wick subject...any thoughts on purchasing the variant covers?  I hate the variant cover concept, but the second variant of Issue #1 looks great.

If you did that, you would receive a Signature Series Qualified label, as the Greg Pak signature would not have been witnessed by CGC.  In my opinion, you would be better off starting with an unsigned copy if you want the book to be Signature Series.
