Forget the computer search. GO to a PAINT STORE and look in their wallpapering books. You may have to visit several different branded paint stores to look at their books as there are many suppliers of wallpaper...and no one store carries them all.
. I have seen it, but not as just US currency. It was a jumble of the different currencies to make the wallpaper interesting.
Im looking for 100 bill printed wallpaper for my house ive been searching all over cant find it anybody ever come across it?
