Artist Josh Bryans beautiful pen portrait of Marilyn Monroe is still one of my all-time favorite artworks of her. (How Id love a print!) Using just black fineliner pens, which range from 0.1 mm to 1.0 mm, Bryan creates triangles of varying sizes until they resemble a familiar face. As he explains to us, The creative process is quite simple. I make sure the image I use as a reference isnt too well-known, even though the subjects are.
