Graffiti Art in Hong Kong

I noticed graffiti in Hong Kong is a lot like that found in Japan. It seems like it's more artists and pop sub-cultured kids that are using this venue for artistic expression; than it is for vandalism or tagging, or gang turf wars, or what have you here in N.America. They all seem to "sign" their graffiti with a stencil, which is not the case in N.America most of the time. Their tag is their signature. I mean, I've framed this "graffiti" so you can see that you could hang it on your wall as art, or put it in a skate or bike magazine, no? Just my two bits......
