I think it's worth noting this quote on reproduction from the same text by Walter Benjamin:
To an ever greater degree the work of art reproduced becomes the work of art designed for reproducibility. From a photographic negative, for example, one can make any number of prints; to ask for the 'authentic' print makes no sense. But the instant the criterion of authenticity ceases to be applicable to artistic production, the total function of art is reversed. Instead of being based on ritual, it begins to be based on another practice -- politics.
There's an book by Theodor W. Adorno (Aesthetic Theory) that tries to, and I believe in quite a few areas manages to, contradict Benjamin's arguments or state that they are limited.
(However this book is quite heavy to read, for this reason I will not try to pick out quotes. But anyone interested the book should in all be a nice point for research if theories are of interest (I have not read the entire book).)
