Through his large-scale, monochromatic photorealistic portraits, Guido creates artworks that are not only inspired by local people, but also aim at giving something back to them. As such, Untitled portrays Peter Hoogewerf, a central figure in the development of STRAAT. The background is an unusual aspect of this artwork, since it was primed with locally sourced sand, aiming to give the canvas a similar look to a concrete wall.
