So quick question, I noticed with the Signature Series, it says that it has to be witnessed by a CGC rep or from the author or publisher.
So if you have a comic with a COA from the artist, will they still count that as signature series?
Also, what about sketch covers with the authors signature. Example is IDW's TMNT #1 RI-D cover variant. They are noted in the comic as all signed and sketched by Kevin Eastman. So if I send one to be graded does it still count as signature series? If it doesn't I would rather keep them ungraded.
Please let me know what you have experienced with CGC, first time using them.
