Is this a notable photograph for visual elicitation? I saw a cow immediately so I thought the references were some weird sarcastic humor... (Not bragging about

  Yes, it's famous. I remember seeing it as a child and taking ages to see the cow, and feeling a "hidden picture" sensation when it finally popped out. Now, decades later as an adult, it immediately and unambiguously looks like a cow. I wonder if that's due to 1) learning the picture, 2) learning more about cows, or 3) learning more about high-contrast images. I do remember hearing that it's one of those things you can't ever "unsee".
