Welcome to this week's What is it Wednesday. A reminder of the rules: Each member gets one guess. The answer will be revealed on the following Tuesday. The first correct guess has the honour of submitting the image for the next challenge. Sometimes there will be more than one thing in the photo or more than one way to accurately describe what the photo represents. The original poster will be the final judge of who is "most correct". So this is second time round hosting, and I've realised I'm terrible at masking the images. So this one could go either way - too easy or too difficult. What is it?
