Reading on signs

As we can see when symbolizes such as man and woman are so strong we will always be able to use it as another universal language.
money
REMIXED
restroom in china
This is a little funny. In many ways will have to say with no question asked any one will still say that this is a sign for the ladies rest room. I think that kn ow matter what this icon will always be associated with the rest room.
man/woman
Its crazy how i never really look at these symbol and wonder how are where it came about. It also brings to meaning how we as humans are so programed to where we always respond to images and associate them with out ever thinking about what we are responding to.
