With Zap Comix #2,3,and 4, I have either a 1st or 2nd printing.
Per this site, the difference is the 1st has "Heavy stock (70 lb.) cover" and the 2nd has "Regular weight cover".
I can't tell which weight the covers are on the issues I have.
Is there any other way to tell 1st or 2nd printing? Or a way to describe how one can tell if an issue has heavy or regular weight covers?
Also, with Zap #2, I notice that with the page titled "Head First" (involving pirates), the bottom panels extend right to the very bottom of the page and does not have the white border at the bottom that the other pages have.
Does this help to tell if it is a 1st or 2nd printing?
Or is this a rarity peculiar only to some of the issues of whatever printing this is?
Thank you for any feedback.
