Residents along the Mississippi Gulf Coast thought Walter Anderson was odd, rowing across twelve miles of open water in a leaky skiff to reach Horn, an uninhabited island without running water or electricity. But this solitary artist didn't much care what they thought as he spent weeks at a time on his personal paradise, sleeping under his boat, sometimes eating whatever washed ashore, sketching and painting the natural surroundings and the animals that became his friends. Here Walter created some of hismost brilliant watercolors, work he kept hidden during his lifetime.
