China has (in this case literally) made an art form out of copying. From clothes and watches to works of art, everything is fair game.
Dafen in Shenzhen is an entire village made up of more than 5000 artists, dedicated to churning out copy after hand-painted copy of paintings by the grand masters, modernists, impressionists, you name it, they paint it. Most go to decorate the walls of thousands of non-descript hotel or office walls but the talent of these "fake" artists is really quite astounding--it's a great place to pick up your own personal version of Da Vinci's "Mona Lisa" or "Sunflowers" for a pittance. They also copy photographs to an uncanny degree and can paint to your request if you'd like something a little bit different.
I came across this great series of photographs by German photographer Michael Wolf on creative trends blog Booooom. Called "Copy Artist" each image shows the Chinese painter posing alongside their imitation creation. Check out the rest of the post and images here.
