Speculation: Artists vs Writers

I mentioned earlier that my Gwenn Wrenn story might make a good graphic novel. I still think it. But, after subscribing to a group dedicated to comic book artists looking for work, I realize it's a project for those with money to spend. They don't want to work on speculation. It's hard to blame them, but it's what I do as a writer. I think my brother Sam would have liked the project enough to do it, but that's just a guess. I once wrote him a script for a comic strip, at his request. He said it would sell, in his opinion, but he didn't wish to work on it. I contacted other artists, without success. So, you never know, dealing with artists. They could be more temperamental than writers, even.
