i found this in a pile of old currency , it contained some colonial notes sheets , and some other odds and ends ..and I was able to identify and confirm they were real ..so this one if anyone has seen a real one can you offer any insight ..paper is blueish gray slightly thick sort of velvety feel..and like 13x8.5 inches large..it has some holes as shown even what looks like a worm hole..but its still intact ..thanks people
