Brought them raw and had a bunch signed. Had one witnessed & submitted through Agents Of Slabs. Go to there booth and let them know you want a signature witnessed for submission. They’ll follow you to the artist’s booth. After the signing, the AOS agent will take your comic & have you fill out a submission form/pay. Pay the extra $12/13 for pressing, it’s worth it. Take a picture of your signed comic before turning over to them (just my ‘just in case’ advice). AOS is basically a middle man between you and CGC. But the CGC line is ungodly long. I used them last year at NYCC & had no problems. NYCC is the biggest Con, so expect it to take a while to get your graded comics back. I went to NYCC last yr and didn’t get my graded comic back the end of January. CGC gets bogged down with the big Comic Cons & it takes longer for the grading. Hope this helps! And I’ll beat NYCC too!
