There is a duplicate entry (81/82) in this list that throws the numbering off.
The numbering should be correct. Issue 81 had the wrong cover listed, that was all. This has been corrected now.
Unfortunately, it’s not quite. There are a couple more issues.
#70 cover is a different magazine with the same title.
73 is missing an entry entirely but the cover is listed under #74.
#75 has 71’s cover.
And all the covers after that are off by an issue number.
The information looks correct for them, just the covers are off. The issue number shows in the upper right circle on the cover.
Here is the reference for the title, if it helps: SCREAM Magazine Archives - THE HORROR ENTERTAINMENT MAGAZINE
Corrected, thank you for reporting.
