Sadly I do not. But at comic shop signings they do not give out certificates of authenticity (at least not at mine) I think only Midtown Comics gives those out at signings. I just went there got to meet him gave him my pictures and got them signed. Though I can tell you the name of the comic shop and given how well I know the comic shop's owner he can confirm I was at the signing if found necessary. Though I certainly understand any hesitation regarding getting a autographs without COA. So cannot blame you for asking. I really wish they did offer those when I went to the signing though.
