I’m working through my Captain Marvel Vol 11 comics and there are some discrepancies throughout the series. I’m going to start with issue 1.
The comic listed as 1AC (Blank cover) is not the blank cover for series 11. It is the blank cover for Vol 10. There is a blank cover for series 11, currently 1AF.
The comic listed as 1AD (J. Scott Campbell - SDCC 2019 - Glow in the Dark) is the same as 7C and is properly 7C.
The comic listed as 1AE, without a picture cover, is likely the same as 1T based on the barcode listed with the issue. I haven’t been able to confirm that yet, but the other J. Scott Campbell issues listed should account for it, thus AE is redundant.
The comic listed as 1X has no cover, but its barcode matches 1U.
