The Scythian Pazyryk of the Altai Mountain region were another ancient culture which employed tattoos. In 1948, the 2,400 year old body of a Scythian male was discovered preserved in ice in Siberia, his limbs and torso covered in ornate tattoos of mythical animals. Then, in 1993, a woman with tattoos, again of mythical creatures on her shoulders, wrists and thumb and of similar date, was found in a tomb in Altai. The practice is also confirmed by the Greek writer Herodotus c. 450 B.C., who stated that amongst the Scythians and Thracians "tattoos were a mark of nobility, and not to have them was testimony of low birth.”
The American Academy of Dermatology distinguishes five types of tattoos: traumatic tattoos, also called "natural tattoos", that result from injuries, especially asphalt from road injuries or pencil lead; amateur tattoos; professional tattoos, both via traditional methods and modern tattoo machines; cosmetic tattoos, also known as "permanent makeup"; and medical tattoos.
While tattoos are considered permanent, it is sometimes possible to remove them, fully or partially, with laser treatments. Typically, black and some colored inks can be removed more completely than inks of other colors. The expense and pain associated with removing tattoos are typically greater than the expense and pain associated with applying them. Pre-laser tattoo removal methods include dermabrasion, salabrasion (scrubbing the skin with salt), cryosurgery and excision—which is sometimes still used along with skin grafts for larger tattoos. These older methods, however, have been nearly completely replaced by laser removal treatment options.
Solid Oak also wants Swain to ignore evidence submitted by Take-Two's experts. It argues a survey about why consumers buy the NBA 2K games is irrelevant; a report that claims there isn't a market for licensing tattoos in video games was written by an anthropologist, not an economist or market researcher; another report that argues the tattoos are rarely noticed in the game is merely speculation; and another expert's report about profits merely states a legal conclusion.
According to George Orwell, coal miners could develop characteristic tattoos owing to coal dust getting into wounds. This can also occur with substances like gunpowder. Similarly, a traumatic tattoo occurs when a substance such as asphalt is rubbed into a wound as the result of some kind of accident or trauma. These are particularly difficult to remove as they tend to be spread across several layers of skin, and scarring or permanent discoloration is almost unavoidable depending on the location. An amalgam tattoo is when amalgam particles are implanted in to the soft tissues of the mouth, usually the gums, during dental filling placement or removal. Another example of such accidental tattoos is the result of a deliberate or accidental stabbing with a pencil or pen, leaving graphite or ink beneath the skin.
