I'm not big on the paper currency but I have not seen this before. The top right and bottom left of the bill have what appear to be a carry over of the "spider webbing". Any info would be greatly appreciated.
its not carry over. at least its not what it looks likeot me. In the lower image that you posted, where you have the UNIT, and TW.... there seems to be 2 very faint 'parrallel' lines to each other, but not parrallel to the design on your note This implies to me that a wet note sat on tp of your note and cause a bit of ink transffer. You can also see similar parrallel lines in the close up of the top of the note. I dont think ink transffer like this is really an error though.
It is probably a "wallet transfer". If you leave two notes in a tight wallet for a long enough period of time the designs will rub off on each other. The same thing can happen with a note that is folded.
