Power of Shazam! #2, signed by Jerry Ordway and features cover and story by Ordway.  Of note, only two Signature Series copies grade 9.8 according to the CGC census and there are no recorded sales of any SS copies coming to market (per GPA Analysis).  Please note, with Signature Series books a certified CGC witness actually observes the signing of the comic and then immediately takes possession of the book so there is no possibility of the real autograph being switched out with another.  It will be shipped with the utmost care.
