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.
Taking over pencilling Justice League of America (after the passing of long-time JLA illustrator Dick Dillon), George Perez finally received his long sought-after chance to illustrate DC's preeminent super-team. Seeing the JLA as a natural progression from his work on Marvel's Avengers, the very reason Perez accepted Marv Wolfman's invitation earlier that year (1980) to illustrate The New Teen Titans was in hopes his work there would eventually land him the JLA. And in 1980, his first year at DC, it didn't take long to realize his ambition. Beginning with the backup Firestorm story in The Flash #283 (Sept., 1980), then his first DC Cover later that month - Green Lantern #132), Perez would then illustrate the introduction of the New Teen Titans in DC Comics Presents #26 (Oct., 1980) with the launch of the teams own title the following month (Nov., 1980). In that month, he would also take over the JLA with issue #184.
He would go on to illustrate #185 and #186, then take about a half-year hiatus before returning to the series with issue #192. This issue, #220, is his 26th and final issue contributing to the series. Perez completely left the title to continue his work on the New Teen Titans and, in 1985, Crisis on Infinite Earths, and would not pencil the JLA as a team again until twenty years later in the 2003 landmark series JLA/Avengers crossover. From the final year of the Bronze Age, issue #220 sports a classic cover by Perez and is part of the annual JLA/JSA team-ups (eagerly anticipated by fans each year, there were a total of twenty-three of these teams ups, beginning in 1963 and only ending in 1985 with the advent of Crisis on Infinite Earths). This, with story by Roy Thomas, is the 20th anniversary of the crossovers.
Signed by Perez, the comic is professionally graded by CGC at 9.6 (NM+) with great eye appeal, and is 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. As of this writing, there are only thirteen Signature Series copies of this book, with three other 9.6's and only three grading higher at 9.8. It will be shipped with the utmost care.
