Sure I doodle on old envelopes, documents and newspapers, but my doodles consist of shaded cubes and poorly drawn body parts. Not those of artist Mark Powell, however. Like the work of Spanish artist Juan Francisco Casas, Mark uses a Bic Biro pen to draw and shade realistic portraits. His canvases are various vintage envelopes, maps and newspapers dating back to 1819.
A friend of mine brought the amazing ballpoint pen drawings of Juan Francisco Casas (actual full name is Juan Francisco Casas Ruiz) to my attention via his tweet, which sent me to this article in the UK's Daily Mail. Only since it was published over a year ago, I was able to do a little research and find his more recent and compelling works.
