User blog:Queso6p7/Jerry Robinson coming to my local comic shop!

When I went to pick up three weeks worth of pulls at my local comic shop one of the "old timer" employees told me that Jerry Robinson, creator of the Joker would be doing a signing at the shop this Saturday! I'm so super-psyched for this! I wonder how early I should go though? Do you all think arriving one hour ahead of time would be sufficient? What are your other thoughts or reactions?
