Comic artist Yuichi Yokoyama (born 1967) draws wordless narratives of scenarios that verge on visual abstraction. Stripped of any detail that might orient them in the past, present or future, they record the self-determined activities of machines and architectural structures in a pre- or post-human universe. With his fourth volume for PictureBox, designed and edited by the artist himself, Yokoyama broaches significant new terrain: color! Color Engineeringreproduces both older and unseen imagery from the 2000s with dozens of color drawings and paintings that were executed in 2010 during a six-week open studio event held in Tokyo, at which the public was able to view Yokoyama at work. A selection of these canvases is reproduced here as gatefold pages, and is integrated among comic-strip sequences executed in a variety of techniques: photography, loose marker drawings, hyper-real portraiture and much more. These sequences continue his investigations into the world of machines, architecture and post-human fashion, and are the first Yokoyama narratives to provide insight into the artist's personal world, in details of his rural habitat.
