There was this record called “Music for Nurses”, whose cover I received back in the old days in way of illusion submission. I never managed to decode the name of the band which was printed as a negative in central position of the cover. Person who sent me this said it was easy, but it took some cheating (Google) before I could see what it says. I decided to share this one, and am more than interested to see how well you manage to decipher the hidden text. Remember not to cheat, and please be honest when reporting how long did it take before you could read it!
