Tattoo shops - The professional tattoo artists will have a selection of work they have done. That work usually can be discovered online. Tattoo artists have a particular style that they favor - doing your research and reviewing the job they may have done in past times gives you the info that you have to make a well informed choice. Remember, these are typically artists that have a vested desire for promoting their work. Should they don't have examples you could view then they will not be an excellent choice. That ink you are getting done will probably be permanent (barring painful laser surgery), make sure that you are making the correct decision.
