pictographic ambiguity

You will probably have come across examples of pictographic ambiguity before, where a single drawing has more than one 'image' contained within it, depending on how you look at it. This picture, My wife and my mother-in-law, is a particularly good example, and was published in 1915 by the cartoonist W.E. Hill. Even experienced psychologists can sometimes find this hard. One clue - the chin of the young woman becomes the nose of the old lady.





There are nine people in the following photo, and I can only find eight (and I'm guessing the dog doesn't count, but who knows for sure). Seeing as how I dislike not being in the know, I'm sending out an s.o.s.;





One more time...This illusion is similar to the young girl - old woman illusion. Here is a helpful hint: the Rabbit faces one direction, and the duck the other.





Just for grins...Is this the face of a "Liar"?





Perhaps this one - lady or a musician - belongs in the Hangout D&D bbs?






Last but not least, Eskimo or Amerindian?






Summation: I just did a google search for pictographic ambiguity or optical illusions and posted some of the results. Although, I never did find all nine people in the second example and have almost driven myself insane in trying to do so. Somebody please feel free to post the answers.

I need to get a life...
