Reprints from the US monthly comic Black Magic published by Prize Publications. Great covers! Tough to find in UK circulation.
#1 has two cover versions - one woth a yellow caption box at the bottom of the cover and one with a red. I believe that the yellow is more scarce/less seen.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
