American sign language zero given shirt

I thought it was universal, apparently each country has their American sign language zero given shirt. That makes it much more complicated.  I’m pretty sure that if americans use these signs with italians, no one of us will understand. Feels good to know that I remembered some of these words, but also cool to know there’s different movements for certain words. There’s a lot of the same signs but for Italy the mean different things like they signed coloring how we’d sign painting.
