Tattoo frogs are a type of American traditional tattoo that has a long and interesting history. They have been around since the late 1800s, and they were first popularized by the tattoo artist, Samuel O’Reilly. O’Reilly was a pioneer in the tattoo industry, and he developed a new tattooing style that featured the use of a single needle, as well as a different ink for each color. This style was known as the American Traditional Tattoo, and it quickly became popular. O’Reilly is also credited with creating the iconic tattoo frog design, which features a frog with a red bowtie.
