These posters came about after I decided to take an earlier project of mine, which focused on just North America, and keep pushing it forward. They depict the major drainage divides of the continents, and are manually printed using the cyanotype process. Each print is unique, with its own individual character. Available in large (42 × 51cm) and small (23 × 19cm) sizes. Click the button below to read more about how everything came together.
