Here are 13 examples and a short bio from Samuel Rodriguez‘s official website:
Samuel Rodriguez is a San José, California based artist whose work has shown in public art spaces, museums, companies, galleries, internet, and editorial publications. Rodriguez was self-taught for a number of years through graffiti until he later pursued a Bachelor in Fine Arts from California College of the Arts. He has since blended what he absorbed from both opportunities to create his current aesthetic. Rodriguez is known for two kinds of portrait styles that he calls, “Topographical Portraiture” and “Type Faces”. Topographical Portraits, are made by stylizing a portrait with topographical lines and shapes in a similar manner to those found through images on geographic maps. Type Faces, incorporate typography and portraiture. Rodriguez developed these techniques in order to explore his interest in social, historic, and cultural hybridity.
