A later addition to the Alan Class family of American comic book reprint titles and issue #1 shows up occasionally on eBay for example, usually low grade, nothing above a Fine. Generally available, even early issues. I've seen 6 or 7 low grade copies of #1 in the last 3 years or so on eBay.
As at Dec 2015 all the cover scans are in but I need to upgrade some so I will keep on looking. Bear with me....
May 2019: upgraded covers for #65, #90, #158.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
