Why do artists do not sign their work?

I do not think that much of the work on the hands of collectors are not signed.

In general, one of the answers can be like that. Not signed as a rule do not complete the work. Do not completed according to the author. It would not put the last point. This is not complete in most cases and there is a good thing.
Work more vibrant, thought they did not break off.
And pay attention. If the signature is painted with a special love, the work shows that the result for the author, the subject of admiration, is just a signature.

A general work, as two drops of water similar to the photograph of the artist.
as a something to show, prove it.
