Good Tattoos???

How do you know you're getting a good tattoo?

 Hell, only time will tell.  

Take into consideration that tattooing has been around for thousands of years- most likely a hell of a lot longer, and we should have a pretty good understanding by now, of what the standards are.  Surely that's why tribal styles of tattooing, the Japanese tattoo, line-based American traditional and black & grey tattoos have stuck around.
