Thought I would post some info. I've come up with on the printing of Zap Comix #3.
I was very confused on this until today going through multiple copies of this. I've found 3 different versions of Zap Comix #3 with a .50 cent cover price.
1st print is a thicker cover stock (reminds me of construction paper) with a MATTE satin finish (it is VERY thick and Very Matte, almost no gloss at all, if you have doubt then it's not a 1st print).
2nd/3rd print uses a heavy glossy cover stock, it's not very noticeable, but compared side by side with the 3rd print you can notice it.
3rd/2nd print has thin glossy cover stock.
So now you know when you're looking for one...
The lowest one is a variant of the 3rd/2nd print I came across that has almost now yellow on the figure running up the stairs.
