Union Haus is Calvin Sprague, Rotterdam based freelance graphic designer & illustrator with a knack for colourful, retro & playful styles. Experimenting with basic lines & shapes, he finds harmony by bridging the gap between structure & chaos. Influenced by the early works of Saul Bass to Heinz Edelmann to Milton Glaser, he sees their eccentric, colourful style as a big reason why he grew to love design.
