Tokenize an Art Asset on the Blockchain

How easy is it for an artist to create a token or asset to represent a real piece of art on the blockchain?

In fact, this seems to be one of the more obvious use cases for the blockchain. There are some registries opening as businesses to allow artists to register a token through their service.
