If it is a raw book or a Blue label, you just have to bring a CGC witness to Mike's table when you pick up the cover. The witness will then bring you back to the CGC booth where you can submit the cover for Yellow label designation. If the book is already a Yellow SS slab, CGC will have to also crack the slab and bring you to Mike's table to drop off the cover. If you are cracking a slab, first make sure that you are actually on Mike's commission list for the show and also plan for enough time for CGC to open the slab (since things can get a bit hectic during a show). Good luck.
