My homecity Zoetermeer, The Netherlands, was the host of a worldwide tattoo convent from april 15 to 17 2017
It was organized by (click on the link):

Sinti Ink.

I visited the meeting several times and the atmosphere was really very relaxed and inviting.
Many people, even from abroad, gathered here to have their tattoos placed by worldfamous tattoo artists.
I made many pictures and if asked nobody refused ever to be photographed.
