Asshole artists would write a fake one but any of them that are serious about selling their art and having it understood tells the truth. Of course people will take it how they see it and may buy it because of what they see not what was intended to be seen , thats life and thats how art gets sold. But every artist wants there pieces intent to be known. At least thats the experiences I have.
