Marvel Preview #21, Moon Knight, Marvel Comics, magazine size B/W comic, Spring 1980, Bill Seinkiewicz Cover, I am not a professional comic book grader but I bought, sold and collected a lot of comics in the 1970s and 1980s. This is an issue that I bought new and have had in my collection since 1980. I believe that this book would grade a solid 6.0 to 6.5 (FN/FN+). However, check out the photos and judge for yourself.
