(I got this information directly from Robert Kirkman....
I agree that there appears to be more of the White warning out there,
but according to him, that's not the case)
The black warning was “first”, and there's more of them, around 7000 or so total.
More than halfway through the print run, the mature readers thing was corrected…
It should have been white with a black drop shadow (making it easier to see on the cover).
About 3000 or so of those, with the white warning, exist.
Both are considered "first prints" and there really is no difference in value
(although the white SHOULD be worth more, IMO, if the above #'s are correct)
I hope this helps!
so according to kirkman, there's 10,000 copies of issue #1? 7,000 compared to 3,000?
i don't think any of us can say we've seen 1/10 of the black labels as we have white labels.
