It's actually not a painting at all.
This mixed media mural is composed of half a million fish hooks. The 26-foot-long piece by Cuban artist Yoan Capote, dubbed Isla, was fabricated by intertwining and nailing over 500,000 fishing hooks onto plywood to create the dark areas—the white bits are oil paint. Even with 30 assistants working in continuously rotating shifts, the piece took over six months to complete.
