|Notes||No OP-1 printing of this poster exists due to confusion previous around it. What were believed to be OP-1 printings were - in fact - the first chronological reprint. |
The OP-1A printined is now recognized as the true original printing, being on vellum at 0.0090" thickness. The back side glows actively under blacklight.
The easiest way to confirm this version against others is by a small horizontal green line through the first "T" in "Tickets" in the bottom left.
There is some variation of color - mostly the green - across the print run.
