Check the faces.

Without being told, I don't think I would even have noticed! Really strange how the same face can be female on one and male on another.

Cool ... I totally missed it too until I read your message

  lol I once saw a greeting card like that. Only on that they were saying as you get older you start to look like each other.

I noticed right away, but then again I do photo editing and facial changes on the computer.

I noticed easily and I couldn't help but giggle.
