Public signs are good indicators of the prevalent behaviours, concerns, or ideal norms in the society. Here are a small collection of such public signs collected randomly during my travels in Japan, South Korea, Thailand, Switzerland, India, China, Ghana, Vietnam, Denmark, and UK. I compiled these photos for THEME magazine article in 2008 (unfortunately the magazine is no longer in publication).
A few public signs are culturally unique. Most of them demonstrate the nuances of the expected norms of the public behaviours. One of my pet interests to write and dig more about in the future.
