Ho do you protect your artwork?

Do you copyright it? or what.
I'm doing a few pieces that will be a very big demand for. I will put about 20 hours into each and don't want joe blow from down the street seeing that they are sellling well so he goes and copies them.

copyright is implicit, you can't really copyright or not copyright something

you have the option to register your copyright ($40 last time I checked)

that's your best bet (before infringement occurs, otherwise your recovery options are just too limited)
