I'm back, yes the notes that I have are Snorter Bank Notes from World War II different countries & with Military Personnel signatures on them, some have up to 20 signatures. I don't have access to the MEK mentioned. I did use warm water to remove the tape, it took 30 minutes to get front & back tape off the right side. However, the water creeped up the note reaching the signatures which started to smudge them as I'm sure that the ink at that time was not waterproof. I let the note dry & it was quite sticky, so I used the WD-40 with cotton ball and that took about 20 minutes, still ended up with rubbery spots, so I just rubbed them off and vola, after an hour I got 1 side done as shown in this attached picture with finished product. Notes are probably worth $1 to $5 with some notes being very thin paper. To sum it up, I'll just leave the tape on the notes. Thanks for the info & help. PC
