Drawing any portrait is difficult enough. Now imagine how hard it would be to not only draw an exact replica of one as famous at The Mona Lisa or The Girl With A Pearl Earring, but do so, without lifting the tip of your pen.

Singapore-base art director and designer Chan Hwee Chong not only drew both beautifully, but did so with such ease that it almost seems like magic! Oddly enough, the whole endeavor was not to showcase his amazing talent, but an advertisement for Faber-Castell's PITT Artists Pens. Pretty Amazing!
