Decorating with fish is no new school of thought. Famous artists throughout the centuries have featured fish in their artworks. Greats like Impressionist Edouard Manet, Expressionist Henri Matisse, Realist Winslow Homer, and pop artist Keith Haring all have notable artworks featuring fish. Wildlife photographic prints, watercolor art prints, and scientific posters make beautiful additions to your home. Go realistic with photographic prints in the den or library. Try dreamy watercolor prints in living spaces or to dress up your powder room. Prop a vintage marine biology poster featuring fish on your entryway console and add a collection of found shells to complete the look.
