His name is Christopher Elsasser and he runs his Etsy shop under the name munstre (pronounced Mun-stir). Most of his work is inspired by anatomy which, if you've ever visited my own Etsy shop, you'd know I've got a slight obsession with :)
Since starting in February 2008, Chris has already been featured in a couple gallery's, shops and even Juxtapoz Magazine.
You can also keep an eye out for his art in the upcoming Bruce Willis flick entitled "The Surrogates" ... I'd say hes doing very well for himself.
