If we explore today's digital age we can see by asking for the authentic copy of something would not make any sense because of the availability of mass production. Also because we can print a lot of copies of our modern art we are always changing what it looks like. Also if we print our first copy of our art usually it is not our final copy before we start to mass produce for a particular purpose. This juxtaposes history for they could only create one design at one time which gives it the authenticity
Walter Benjamin said "That which withers in the age of mechanical reproduction is the aura of the work of art.” I think our modern society has highlighted what Benjamin has said here. Our mechanical or "digital" reproduction has taken the Aura or “Authenticity” out of the art work. Things that we have created in the 20th century won’t have that the same authenticity as in the 19th century because we can mass produce it and change it in so many ways.
