I can tell you where the green background is supposed to have come from: the Hawaii folks say that they printed their image on green “safety paper.”
Do you have a source for this? I did a quick search but don't seem to see an obvious source.
Yeah, so I heard. Was it something like the one linked below? I didn’t have any “safety paper” handy, so I had to “borrow” some. Does the pattern look familiar? Feel free to “download original” from the FILE menu, and examine it. I don’t think your going to find multiple layers of artifacts and doctored text in this one.
