This is a Spider-Woman #1 Blank Sketched and Signed by Steve Leialoha, and it has been graded by CGC 9.8, and the Certification Number is 1475673008. The comic was sketched and signed at the 2016 San Francisco Comic Con on September 2, 2016, at the San Francisco Marriott Marquis in San Francisco, CA. The comic was sketched and signed at an event that CGC was not at so therefore they will not authenticate the art or the signature. It will pass any third-party authentication with no problems, so I hope you will take my word. If you do take my word, you will be getting a one of kind original artwork by Steve Leialoha and if you do not believe me, you will be missing out. The graded comic will be shipped securely with a tracking number and insurance. If you have any questions, please ask before you buy.
