To be honest with you, I?ve never even heard of that before, and I?m a guy who is covered from scalp to ankles with tattoo
Many tattoo artist will ask you or even require you to allow them to take a photograph of their work and put it in their album or on their Instagram or social media pages
The only thing close to being a tattoo model that I have seen is a tattoo conventions where somebody is doing getting a tattoo done right there at the convention and then enters into the competition each day at the end of the day
