About the item:  

Action Comics #647, signed by hand by Roger Stern, George Perez, and Brett Breeding and JSA authenticated through CGC with a grade of 9.4. Features the first part of the "Brainiac Trilogy."  Fresh from CGC, it will be shipped with the utmost care.  Of note, the comic is from the collection of Roger Stern.  It was purchased directly from him at the 2018 Terrificon at Mohegan Sun and is one of his personal comp copies (i.e. comics set to the creator by the publisher... in this case, DC Comics).  So it was personally owned by Stern himself. Comes with a VaultCollectibles COA which notes it is from his collection (sample COA shown in image 3 above).
