That's a common defect on many early to mid 1960's Marvels. It bothers some people. I personally don't think twice about it as I just look at as a part of Marvel's history.
Oh, absolutely. That said, to me it seems like this issue in particular has a way higher % of off the mark staple placement than any other SA Marvel that I've ever been interested in (for example, the rest of the Ditko Spidey run)
I agree with you on that. I don't see it that often on other Silver Age Spidey's (staple placement on the front). Maybe there's a reason for it being more prevalent on this issue?
