That was something that raised my eyebrow for sure, then I saw that the 5, the 10, the 50 and 100 dollar bills could all be folded similarly, and showed the progression of the collapse, the Pentagram building, etc. The coincidence theorists of the world must have a lot of trouble with that particular conspiracy theory!
Thanks for the image, haven't thought about that in a while. Those larger bills change all the time in design, but the mighty ONE never changes, it has a function of its own.
