So I know at the time there was a huge debate on the 1st / 2nd printings of this poster around the ComicCon convention, and that there were some differences between the two, the first printing being more "pink" than the "red" second printing. I also remember microscope images that although were pretty obvious, obviously required a microscope to see.
Does anyone know how to differentiate between the two printings with the naked eye, i.e. something I could ask a seller to point out to me before I buy? I already own two copies of what I understand were the 2nd printing, but not having a microscope, I can't even be sure of that, let alone buy another copy of the printing I already own from someone who can't tell me.
Any help would be appreciated, as I am both interested in obtaining a first printing if in fact I own a second, and selling my second copy to someone who is interested in only a first printing.
Thanks!
