The signature drawings are of great importance to art protection. A painting without a signature can be easily copied or stolen. Moreover, the artwork does not look complete without the sign from the artist. Over time, the painting with a signature can increase in value, while the nameless one will be hard to identify. They will not be equally evaluated because of doubts about the origin. If you become successful and popular around the world, your signature becomes valuable too.
Another reason for signing your work is that you will tie all the pieces together with the signature. Even when you have parts that look as if they aren’t connected, you can unite them using a signature. Consider your signature on paintings, manuscripts, and music notes as the logical finish.
You can’t send your creation to anyone or show it to other people without your signature unless you take part in some competitions where your true identity must stay hidden. However, in the end, you have to reveal your name even in such cases.
