Vanity Galleries

I received an email from a gallery in a desirable location in New York City which will exhibit your work for a fee. The original posting detailed verbatim their letter describing their services. I described it as a "vanity gallery" and said "I haven't heard anyone benefitting from this kind of relationship. It has been described to me as not really having a relationship at all, as one might have with reputable galleries. I have heard stories that wealthy but new to the practice of art buy into this and have a show.
And interesting article about vanity galleries here.

The gallery then sent me a threatening letter saying it was going to sue me for slander. So,i have removed the letter but still believe that vanity galleries are to be avoided.
