Regarding the comics industry recent reholder scandal / scam, please note that all books I sell were submitted directly by me to CGC at various comic conventions (as well as the occasional private signing event).  I do not buy already graded books and then resell them.  So every CGC item I have for sale was graded by CGC and then came directly to me and not through another dealer.  Please further note that photos, prints, and original art sketches (that are not on actual comic books but are rather just on sketch paper or the like? i.e. anything certified by CGC that does not have a grade, are not searchable on their site by the serial number.  Only graded comics and magazines - items with grades - are searchable by serial number.  However, for such items not searchable on their site, you can call CGC Customer Service and they can verify the item authentication over the phone.  

About the item: 

Graded by CGC at 9.2 and signed by George Perez, this issue features George Perez's very first published DC cover.  The issue also launches a new Adam Strange backup feature, the characters first solo story since 1970.  Is professionally graded by CGC and certified as part of their special Signature Series.  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.  As of this writing, according to the CGC census, there are only twenty-three Signature Series copies of this book- three copies that grade 9.8, three copies grade 9.6, five at 9.4, four at 9.2, two and 9.0, two at 8.5, one 8.0, one 5.5, one at 5.0, and one at 4.5.
