Tattoo Old School is the Western, traditional Americana style that was made famous by Norman Keith Collins, better known as "Sailor Jerry." It's also written as Oldskool or Oldschool. Usually the style uses bold black outlines and standard classic colors like red, green, blue, yellow, brown and purple. The style is not realistic and does not feature detailed shading. Some very popular Tattoo Old School subjects feature anchors, hearts, pinups, roses, swallows, daggers, eagles and mermaids. Because this style is based on sailors who saw the tattoo cultures of Polynesia and South West Asia, the subjects are often nautical based.
