In Greenpoint where I finally lived for over 5 years, every bill that passed my hands were always marked or stamped. As if the regular markings weren't cryptic enough already.
My friend L___s paid rent in 100s, and almost 80 or 95 percent had these type of marks on them. It was interesting enough for this one piece, too novel to keep doing. Had a little to do with leading me to my other money work later.
