I'm going to be attending DragonCon in Atlanta during Labor Day weekend, and I'd be glad to accept your items on consignment. Please see the convention's website at www.dragoncon.org for details on the show's impressive lineup thus far.
Unfortunately, the annoying "CON"-pun intended-about this convention is that they have not posted autograph prices in advance. Therefore, we will have to make educated guesses based on past pricing. For example, it's pretty much guaranteed that Shatner will be $75-I think we can all agree on that, right?
Please email me at email@example.com as I rarely check the boards here on Autograph Live-I'd love the chance to help you for this and future shows.
