I'm on eBay looking at Marvel Transformers from 1984 but there are two covers. One has a bar code the other has a black head of spider man. I've been searching with google trying to find a reference to 2nd prints and what if any variation on the cover would identify it as such. Is the spider man picture indication of a reprint? there is also a diference in the area where the date is, but the date is the same.
