They say an artist is never recognised until after they're dead. Sometimes it's because their worth is exaggerated by the immediate stop in production of works. Sometimes it's because they die in interesting circumstances. Sometimes it's because only then are they actually recognised by their agent.
One of my clients was not recognised when he was alive. I could never promote his stuff because it always seemed derivative, copied, an old idea or at least one that had been recently revealed. I used to get captivated by his pseudo anger at it, that he couldn't be original. He did keep up this constant act of being original, but always just too late. It was always too obvious he'd just copied someone else's work.
He came to his grisly end just like he lived his life. I remember hearing about the death of Brandon Lee, then literally, only a few days later, I find my artist has "accidentally" shot himself with a crossbow that was meant to be firing paint sticks at him. The idea seemed to be like paint balling but with crayons, I guess he wanted to hook into that accidentally killed by blanks thing, but it didn't work.
What I did manage to work in was the fact that he copied. Up until that point, it had always been a problem, but now he's dead I'm making quite a profit from the plagiarist.
