For those peeps who freak out at the commitment or thought of getting so inked, then check out this research: A small study at the University of Alabama found that those with multiple tattoos showed a better immune response to new ink than those who were going under the tattoo gun for the first time. This suggests that tattooing might stimulate the immune system, like how a vaccine does.
Mainstream art galleries hold exhibitions of both conventional and custom tattoo designs, such as Beyond Skin, at the Museum of Croydon. Copyrighted tattoo designs that are mass-produced and sent to tattoo artists are known as "flash", a notable instance of industrial design. Flash sheets are prominently displayed in many tattoo parlors for the purpose of providing both inspiration and ready-made tattoo images to customers.
