Oliver Peck has become a household name in the tattoo industry since he joined the cast of the popular reality show Ink Master in 2012. Peck is renowned for his speciality in traditional American tattoos, which is the most popular genre of the art. Traditional tattoos, also known as old school tattoos, are characterized by bold lines, vibrant colors, and classic designs that are usually inspired by American icons such as pin-up girls, American flags, and eagles. They are often heavily shaded and depict a nostalgic, vintage feel. While the genre has been around for centuries, Peck has been credited with bringing it back into the spotlight in recent years.
