Tattoos have been around for centuries, and throughout the years, the art of tattooing has evolved in many ways. One of the oldest and most popular styles of tattooing is the American Traditional style, commonly referred to as "Traditional" or "Old School." American Traditional tattoos are characterized by their bold lines and classic colors. One of the most iconic symbols in American Traditional tattoos is the eye, which is often depicted in the form of a tattoo flash. It is believed to bring protection and good luck.
