I haven't seen it before. Maybe it's the start of a trend....
It's not the first poster with an infrared image, if you remember the
Predator posters of yore, although one could say that the very rare
Predators poster is a new trend, that is continuing on with the old school
Predator posters. Which begs the question: would you rather be in on something at the beginning of the trend or at the end?
If you haven't seen it before, then how was that price "unexpected." The Poster Price Police would have a difficult time saying that price is too high if there are few or no other prices to compare it to...
