Tattoo
From FOnline: 2238 Wiki
There are two places from where you may obtain a tattoo, New Reno and San Francisco. The price for getting a tattoo is 500 caps. Do not forget that the maximum length of phrase is limited to twelve characters.
New Reno:
You can get a tattoo at New Reno from inside Commercial Row. Watch out for player killers who come here regularly to fight others or camp the area.
San Francisco:
The second place is San Francisco, inside the city by the brahmin pen. This is a guarded town, but it's also very far away.
