Postmodernism can be described in many different ways but boiled down, it can describe anything that comes after the modern movement. As the modernist movement was was defined by sleek minimalism, it is fair to group excess and decoration into the curl of postmodernism.
While the number one rule of design is Function before Form, postmodernism likes to toe the line. This can be seen in the work of Post Modernist designer Karel Martens.
Karel Martens is a Dutch-born graphic designer, specializing in typography. He has created works in a variety of deliverables, such as posters, prints, postcards, editorials, etc. His work is the opposite of the fancy and elegant aura of modernism; it’s rather colourful and playful.
He created an entire mono print series entirely using things he picked up off the side of the road, such as scrap metal, old car parts, and garbage. His longest running (and current) project is the Stedelijk print collection in which he is using old archive cards from the Stedelijk Museum in Amsterdam as canvases for screen prints.
I personally love his world. He takes old, dry, boring materials and turns them into something colourful, full of life and Postmodernist. I look forward to seeing more of his work in the future.
