So I bought the Ultimate Jim Lee CGC Experience. His signing will be on Saturday, May 4th. The issue I have is whether I can other signatures from like Scott Williams, Doug Mahnke and James Tynion etc on a book before this special signing. Would a CGC rep onsite be able to hold the books between signings? There is a private signing experience with Tomasi, Mahnke and Tynion on Friday and Id like to get Detective 1000 signed by everyone for grading. What is my best option here? Should I just do the Lee signing Saturday and hope to get everyone else after with a CGC witness?
