Signs

Signs are a funny thing, they are. Last  time I posted an image of a curious one found in elevators in Sweden. At second thought I don't think it had any thing to do with ties. I still don't know what it means, so if you know its significance, please inform me. 

Signs can be confusing. For example, my friend told me this one meant: "Careful! Heavy umbrella!"

Well it doesn't mean that. It means Men at work. It's confusing so I suggest a better sign. An international one:

Men at work
