1920
A New York tattoo artist, Samuel Reilly, invented the electric tattoo machine in 1891. He adapted Thomas Edison's design for an electric pen, in which a reciprocating motor powered a needle, to create a tattoo machine that was faster and less painful than previous hand methods. The machine needed to be portable because early American tattoo artists traveled constantly along the eastern seaboard, selling their craft to sailors at the different ports. Needles of various sizes, a bottle of hydrogen peroxide and a small bottle of tattoo ink appear inside this box.
