Todd McFarlane is listed on the exclusive portal for one item autograph at SDCC at the DC booth on Thursday. I'm aware of the arrangement he has with CGC and only specific shows will they provide CGC witnesses. The description on the exclusives portal doesn't say anything about CGC witnesses not being allowed for this one. For his later appearances at an Image booth, it does mention no CGC though. (but those aren't ticketed through the exclusives portal)
Does anyone happen to know if I will be able to get a CGC witness to accompany me. if I am lucky enough to get selected for an autograph through the portal?
