He's not going to just make a salad for himself. Some backers will receive "a bite" of the salad (and the guy will say their names out loud while making the salad). And the whole Internet is invited too. :)
I am deeply sorry to let you know that, after inspection of your item, I had to report it to ebay.com as a fraud. From the image, it's clear that what you are selling is a photograph of the original work from the mentioned artists. This is indicated by the reflection of the camera flash on the screen the piece of art was displayed on. According to the e-commerce rules of ebay, copy of pieces of art must be explicitly indicated. I would be interested in buying the original, though.
I am not sure why you would give him this attention if you don't want him to be seen? does not make sense. It's like the idiots who make Justin Bieber famous by hating on him.
I don't really care that much, let him do as he feels he wont get much of my attention though(as long as people like emph don't post about him or talk about him)
