Old  school tattoos were actually modern tattoos of yesteryears and were  pioneered by Samuel O’Reilly from Boston.  However, old school tattoos  are said to have been born at Chatham Square in New York as this is the  very place where Samuel O’Reilly started his shop. Samuel took an  apprentice named Charlie Wagner who carried forward the business in 1908  when Samuel passed away. Wagner joined hands with Alberts who has  trained as a wallpaper designer who utilized his skills to design old  school tattoos.
In  1961 the tattoo practice went further underground following the  outbreak of hepatitis. Although many tattoo shops were using  sterilization machines, there were news rumours about blood poisoning,  hepatitis and other lethal diseases. The New York City government  decided to regular tattoos businesses and enforced a health code  practice for the tattoo designers. Following this regulation, many shops  at Times Square and Coney Island were shut down, and there was a time  when it became tough to find a tattoo shop in New York City.
However, tattoos have re-emerged as an accepted art and are now popularly termed Nu School (New School) tattoos.
