Triton is the largest of Neptune's 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet's rotation―a retrograde orbit. It is possible that Triton has subterranean seas, an idea that has captured the imagination of our illustrators. Celebrating the vintage art and designs of space travel from the early and mid-20th century, Anderson Design Group has created an adventurous aquatic space fantasy design that will look great as an art print, poster, notecard, postcard, metal sign, canvas, or mini canvas. Choose from multiple size options, frame designs, and more!
