Earlier quoted context omitted.
That $5 pound note looks great, I love the white sides with the emblem of the notes in general. But the pattern remains, those bills are for the most part extremely dense and overflowing with information and layered graphics. Especially the existing $50 one which is crammed full of stuff. It's like someone came up with a list of ideas and said yes to all of them.
It's mainly an anti-counterfeit thing to have that much info on them. Fact is, there's even more that you can't see, there's microwriting on them too (can't find an image, but on the £5 and probably all others) and it's almost unnoticeable without magnification. Can anyone find an image of this?
