I have a 1930's Art Deco waterfall edge vanity that someone painted, what is the best way to restore it?

I not only want to restore it because of it's look but also to regain some of it's value if possible.  Right now I have a wood board on top of it to make it one level and to protect the top and am using it as a desk.
