Calvin Sprague, a Rotterdam-based graphic designer and illustrator from the United States, is the creator of colorful, retro-inspired works. Before settling in the Netherlands, the artist lived in Texas for a long time, then decided to travel to Europe in order to find inspiration and start his own business: Union Haus. His illustrations stand out with fine curves revealing colorful shapes, thus creating surreal and recreational scenes, and finding his own balance “by bridging the gap between structure and chaos”. His creations are available for sale in his online store.
