I'm relatively new to CGC, and have only submitted two books for signature series slabing. The first time was a direct submit into CGC, at New York Comic Con this past October, to have Robert Kirckman sign a Walking Dead book. The second time was this past November at New Jersey Comic Expo for a witnessed signature of Jae Lee. I noticed when both books came back to me, the label only said sign by __________ on this date. Not sign by __________, the date, and the con they were signed at. I've seen CGC SS books on eBay, and online, with the cons that the books where signed at; listed on the label. My question is, for my next submission, how do I get CGC to list on the label the cons that I've got the individual books signed at. Or is this simply something that CGC doesn't do?
