It was a while back.
I think the conclusion was that these prints sell well but are kind of tacky. I think if they do sell well, it's going to be on the low end. Since you're a gallery artist, I'd steer clear.
It's important to keep up certain standards. I mean, if you want to be a customer pleaser - then go for it, but if you want to be taken seriously as an artist, I'd be very careful. Given that your work is so accessible, I think it's especially important that you maintain a level of professionalism and quality in your product.
