Headless Zebra or Painted Burro or Back End of a Horse!

Some photographs turn out unintentionally amusing, like this one of a donkey -or burro...or zebra.... in a Mexican street. I had hoped to capture the whole of the animal, but of course he had to dip his head just as I took my picture. I am inclined to believe the animal has merely been decorated to look like a zebra, the clue being the "graffiti fest" banner in the background. The stripes seem to be fading a bit around the middle of the animal, adding to the surrealistic nature of the picture. Location: Tijuana, Mexico
