Growing up I always used to admire murals, whether they were in El Paso or anywhere else. Something I noticed was that a lot of graffiti murals were signed C/S, but I never knew what it meant and no one ever told me. Years passed and I didn't think about it's mysterious meaning until last year when I went to Los Angeles and saw some of the murals. Sure enough some of them had the C/S. Not only that, but I read a book called Drink Cultura by José Antonio Burciaga and it has a chapter dedicated to Con Safos. He signs off every chapter with an C/S. That is when I learned it's meaning.
No one knows the exact origin of Con Safos or who was the first to use it, but it is used a lot in graffiti. Con Safos literally means "with safety". "It was meant as a safety precaution, a barrio copyright, patent pending." (Burciaga, 1993) Con Safos is like an honor code or even an "amen". In other words it means "anything you say against me will bounce back to you." (Burciaga, 1993) In literature, the C/S is also more of that of an "amen."
Burciaga does a good job of explaining it, I finally understand why it's so important. Every time I see one, I smile back in respect. I hope everyone can one day why it is important: both symbolically and culturally.
