We can say for sure that Linda Huber is a true artistic freak. She is dedicated to making incredibly realistic pencil drawings.
She claims that she is a self taught professional pencil artist. She spend about two to four days approximately while drawing one portrait.
While looking on her drawings, you will be amazed how they are realistic. When I first saw them I believed I am looking at some gray-scale photography but no, all of them are drawn by hand.
